Answer:
A'ight
I'll use the symbol "£" as theta
don't have that on my keyboard.
Step-by-step explanation:
So
y=£^3(√1+cot²£/csc£)
csc is the short for cosec
Recall
from Trigonometry
1+cot²£ = cosec²£
So √1+cot²£/cosec£ = √cosec²£/cosec£ = cosec£/cosec£ = 1.
y=£³
Integrating
you have
y= £³+¹/3+1
y= £⁴/4 or 1/4£⁴ + C
Have a great day!!
