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:
You may just add 2 in the spot. Moreover, you get no solution.
Step-by-step explanation:
Hope this helped!
All you have to do is rotate the current dots, and bam.
Divide the total amount charged by the number of hours worked, and you have $/hour
