Answer:
-1
Step-by-step explanation:
We need to find the value of tan² 70° -sec² 70°.
We know that,
...(1)
We can write the given expression as :
tan² 70° -sec² 70° = -(-tan² 70° +sec² 70°)
=-(sec² 70°-tan² 70°)
Using identity (1)
=-(1)
= -1
Hence, the value of the given expression is -1.
The limit of the expression as x approaches -3 is -24
<h3>How to determine the limit of the expression?</h3>The expression is given as:
As x approaches -3.
The limit expression becomes
Substitute -3 for x in the expression
Evaluate the expression
Hence, the limit of the expression as x approaches -3 is -24
