Simplify the expression.

cos x cotx + sin x

a. 0
b. csc x
c. tanx
d. sec x

b. csc x

Step-by-step explanation:

cos x cotx + sin x

We know that cot = cos/sin

cos x cos x/ sin x + sin x

cos^x /sin x + sin x

Getting a common denominator of sin x

cos^2 x /sin x + sin x * sin x / sin x

cos ^2 x / sin x + sin^2 x / sin x

( cos ^2 x + sin^2 x) / sin x

We know that cos ^2 x + sin^2 x = 1

1 / sin x

We know that 1 / sin x = csc x

csc x
