Question

if cot theta = 7/8 find the value of (1+sin theta ) ( 1-sin theta )/(1+cos theta ) (1-cos theta)​

Answer 1

Answer:

cot theta =7/8

now

(1+sin theta) (1-sin theta)/(1+cos theta) (1-cos theta)

=(1-sin^2 theta)/(1-cos^2 theta)

=cos^2 theta/sin^2 theta

=cot^2 theta

=(7/8)^2

=49/64

Step-by-step explanation:

using (a+b)(a-b)= a^2 -b ^2

Answer 2

Answer:

$\frac{49}{15}$
