Angle 1 and 2 is complementary agles
Csc²x - 1
1/sin²x - 1
1/sin²x - sin²x / sin²x
(1 - sin²x) / sin²x
Recall that sin²x + cos²x = 1
So cos²x = 1 - sin²x
So we can replace numerator to cos²x
cos²x / sin²x
= cot²x
Final answer: cot²x
C adding a number to itself
Answer:
Can you type out the question? it is hard to read and the angle makes it harder
