Question

if cottheta=7/8 then evaluate (1+sintheta)(1-sintheta) /(1+costheta)(1-costheta)​

Answer 1

Answer:

Using the identity

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

Answer 2

Answer:

upon numerator calculation we get cos ^2 theta , upon denominator calculation we get sin ^2 theta

Step-by-step explanation:

by question we get cot ^2 theta

which is (7/8)^2

49/64
