What is an antiderivative? And how do would you do this problem?

D) ∫ˣ cos(t² − 5) dt

Step-by-step explanation:

"Antiderivative" is another name for integral.

∫ cos(x² − 5) dx

This can also be written as:

∫ˣ cos(t² − 5) dt

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
