Question

plz help I fell very difficult to learn trignometry, all other chapters are easy, plz help me by telling how to read and the important things except formula and values
​

Answer 1

Answer:

here are your answer buddy...

most of us feel this chapter as difficult. it is basically true. but not every time.

application of trigonometry us much easier than proving the trigonometry...

i think you will never find difficulty in applications.

but you will be lagging for proving sums in trigonometry.

here are some easy methods to know....

• first always read the question twice or even thrice to understand the question....because ncert syllabus gives you always twisted questions in trigonometry.
• understand the concept that they have used...to understand these concept you have to do more hardwork...
• refer example sums too.
• don't go with reference book.they always confuse you.
• for trigonometry chapter, book somes are enough to practice. and ncert will not give the sums out of book sums.
• so be thorough with book sums.
• i had to definitely say that some sums are have to be remembered to score better.
• after understanding the concept, try everything that you know. no matter right or wrong.
• for trigonometry you will definitely have to scribble in your exam paper.because I'm to scribble in my examination.
• if you got the answer that's good but if you didn't get no problem...if you need to prove the sum you can do anything.
• for example if you need to proof LHS=RHS.., multiply zero on both side, no matter.. because some time the checkers may not observe these steps...
• always wirte trigonometry sums at last. but from starting you have to write smarter so that checkers may feel good impression on you.
• then at last the checker will never mind about sums.. because they came to know that you are a brilliant student.
• practice is the only solution for the trigonometry chapter.
• my last point is that be thorough with book sums.
• it is more than enough for trigonometry chapter.
• but for application you have to do extra sums with the reference books.
• don't see RDsharma at last time. it will never give you advantage.
• refer Exam idea, together with...
• it is more than enough.

hope you will understood my points..

and score better in your examination.

Answer 2

Answer:

mark me the brainliest

#answerwithquality #bal

Step-by-step explanation:

Helpline with values:

• Write 0,1,2,3,4 in ascending order.

           0          1          2           3          4

• Divide throughout by 4

          0/4       1/4      2/4       3/4        4/4

     =   0           1/4        1/2         3/4         1

• Put root to each of them

          $\sqrt{0}$       $\sqrt{1/4}$       $\sqrt{1/2}$       $\sqrt{3/4}$       $\sqrt{1}$

    =    0        1/2          1/√2          √3/2       1

Now these values are the sine values of 0°   30°   45°   60°   90°

Reverse of this order is the increasing cosine values of the same angles

tangent of these angles are sine/cosine

                              ⇒ tan  = sin/cos

cotangent (cot) of these are the reciprocal of tangent (tan)

                              ⇒ cot = 1/tan = cos/ sin

Also, secant,              sec = 1/cos        

 and cosecant,          cosec = 1/sin

Mostly remember (tan 30, 45, 60) (sin 30, 45, 60, 90) and (cos 30, 45, 60).

Rest are the reciprocals of these.

If you are saying trigonometry is really difficult, learn at least those sine values, rest can be found by various ways (I have mentioned my trick above).

Then,

             just remember sin²Ф + cos²Ф =1

Rest of the formula arise when this equation is divided by cos²Ф and sin²Ф.

(sin²Ф + cos²Ф =1)/cos²Ф = tan²Ф + 1 = sec²Ф

(sin²Ф + cos²Ф =1)/sin²Ф =  1 + cot²Ф = cosec²Ф

A value x its reciprocal = 1

tanФ cotФ = 1

sinФ cosecФ = 1

cosФ secФ = 1

• When a qus is asked, read minimum 4 times the qus. Vocabulary should be good enough to assume the conditions given.

• Drawing a rough figure is important.

• NCERT provides the best of best qus as examples, exercise and miscellaneous qus.

• Before the exam, you must do all the qus thrice. Even twice is fine.
• While doing a qus, do it twice or thrice no matter how easy or small the qus is.
• While preparing a difficult or HOTS should be done minimum thrice of similar type or the same only after understanding the qus.
• Formulas should be byhearted.
• Clarify doubts with friends or teachers itself. Only a direct interaction can help you with a numerical qus.
• R.D Sharma Books provides additional good qus which should be refereed and done once.
• Don't worry, the teachers will give some marks even if you got nervous and screwed up. But be cool and answer as if you feel there is no qus they will be able to screw me.
• Jus practice and slay them.

Honestly am telling you, trigonometry is most easiest chapter with which you can score full marks.
