Differentiation and trigonometric integrals
Good afternoon everybody! I recently started taking calculus 2 at university and the class picks up like we never missed a day between calc 1 and calc 2. We jumped right in and I'm rather rusty. I use khan academy often but was hoping somebody could help me review/teach me with differentiation and trig integrals.
Anyways, here are my problems that I'm working on. Yes, they're rather simple but I've not done calculus in 4 or so months:
Differentiate:
1. y= 4x^3 -2x
2. y= sqrt(2x-4)
3. y= x^3 tan(x)
4. y= sin(x^2)
5. y= (x+4)/(x-2)
Integrate:
6. ∫ (cos x- sin x)dx
7. ∫ sqrt(x)dx (Definite- solved at 4 and 1)
8. ∫ cos(x^2)xdx
9. ∫ (sin^2 x cos x)dx
10. ∫ (tan x sec^2 x)dx
Those are the questions I'm currently working on. I'd just like somebody to discuss something related with me or check my work. Thanks in advance! :)
