Question

If Sin 0 = 3 /5 ; los o 4/5, what
will be the value of tan o ?

Answer 1

Step-by-step explanation:

If sinΘ=

5

3

Then, opposite side of the right angled triangle containing angle θ=3 and hypotenuse =5

Using pythagoras theorem, we get the adjacent side =4

Now we have, cosΘ=

Hypotenuse

Adjacent

=

5

4

And tanΘ=

Adjacent

Opposite

=

4

3

So,

3sinΘ+secΘ

tanΘ−2cosΘ

=

3(

5

3

)+

4

5

4

3

−2(

5

4

)

=−

Answer 2

Answer:

3. The sum and difference formulas. 4. The double and half angle formulas. 5. Product ... cos t cott = 1 tan t. = cos t sin t . Table 6.1: Reciprocal and Quotient Identities. 4 ... 1A function f is odd if f(-x) = -f(x) and even if f(-x) = f(x) for all x in its domain. (See ... As indicated, the formula is valid as long as 1 - sint = 0 or sint = 1.
