The ratios are 3:5 for the first one and 4:10 for the second
Get all numbers into the same form : ounces
1pound = 16 ounces
16 + 7 = 23 ounces
23 divided by 2 equals
16.5 ounces.
Evaluate int[sin^3(θ)cos(θ)dθ] with u = sin(θ)
du/dθ = cos(θ), dθ = du/cos(θ)
The integral becomes:
int[u^3•cos(θ)du/cos(θ)]
= int[u^3•du]
= u^4/4 + C
Substitute u = sin(θ) to get back a function of θ:
sin^4(θ)/4 + C
Combine like terms:
3/4-1/2=1/4
-4z+5/4z+1/2z=-2 1/4z
so your answer is -2 1/4z+1/4
