Answer:
1) ∫ x² e^(x) dx
4) ∫ x cos(x) dx
Step-by-step explanation:
To solve this problem, eliminate the choices that can be solved by substitution.
In the second problem, we can say u = x², and du = 2x dx.
∫ x cos(x²) dx = ∫ ½ cos(u) du
In the third problem, we can say u = x², and du = 2x dx.
∫ x e^(x²) dx = ∫ ½ e^(u) du
Answer: if i am correct it should be 144y
Step-by-step explanation:
12y ×12y=144y
Its exponents but im not sure.
I don't know where the angle β is, so I will make the assumption that tanβ = h/r

V volume = 60
r radius = 2
h = r tanβ
