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:
We want to find .
By definition:
Since we want to find the Left Hand Limit, we use f(x)=-(x-2)
.
.
The limit of a constant is the constant.
