This is my first time doing a double integral, so im only 90% sure in my answer
Step-by-step explanation:
You pretty much want to take the double integral of sinx + cosx
The anti-derivative of sinx = -cosx
The anti-derivative of cosx = sinx
So f' = -cosx + sinx
Now lets take the integral of f':
The anti-derivative of -cosx = sinx
The anti-derivative of sinx = -cosx
So, f(x) = sinx - cosx
Hi there!
Begin by solving for the area of the base:
A = 1/2 (bh)
Thus:
A = 1/2(2 · 1.5) = 1.5 in²
Multiply by the depth to find the volume:
A = 1.5 × 7 = 10.5 in³
