Show that SinA(cosecA-cotA) =1
Answers
Answer:
Step-by-step explanation:
There is a bit problem in the question I guess dude...
Well thanksss for asking the question and I’m seriously very very happy to clear and chart your doubt here...
Your question I would like to recap is:-
SinA(CosecA-cotA)=1
But I would like to correct it..it is not 1..it should be .....1-cosA.....
So let’s have the soluTion according to me...
See friend..as you may know ..that whenever (as this question is of junior level)...thee is terms like cosec,tan,cot..just convert them first with the...sin and cos as it is easy to operate the things..-!: may surely help you...
So let’s begin the journey...
=)sinA(1/sinA-cosA/sinA)
=)sinA(1-cosA/sinA)
=)1-cosA
See now..in this question firstly we have converted cosec and for in terms of sine and cos as..cosec is 1/sin ..and cot is cos/sin...
Later we did with the LCM..and in last step we cancelled sinA with SinA..and this got the cosA-1...which is the required answer according to me ...
Hey!!hopi I helped you..
Thank me later_!!!!
