Question

answer 6th one step by step​

Answer 1

COT X=7/8

COSX/SINX=7/8

SO

(1+SINX)(1-SINX)/(1+COSX)(1-COSX)

=1^2-SIN^2X/1-COS^2 X

AS WE KNOW

SIN^2X+COS^2X=1...EQ1

={COS^2 X/SIN^2X}BY EQ1

AS WE KNOW

COS^2X/SIN^2X= COT^2X

SO COS^2X/SIN^2X=49/64

SO

1+SINX)(1-SINX)/(1+COSX)(1-COSX)= 49/64
