Rewriting the left hand side,
csc²t - cost sec t
= (1/sin²t)-(cost)(1/cost)
= 1/sin²t - 1
= 1/sin²t - sin²t/sin²t
= (1-sin²t)/sin²t
= cos²t/sin²t
= cot²t

Answer:

Step-by-step explanation:
The given function is
If a function reflected over the x-axis, then x-coordinate remains same but the sign of y-coordinate is changed.

If function f(x) is a reflection over the x-axis to get the of g(x), then the resultant function is
Substituting the value of function f(x), we get
Therefore, the required function is
.
