1. The problem statement, all variables and given/known data

I have 3 problems that i am struggling to solve for the simple fact that there are two variables in each problem. I have no experience with multivariable calculus... i feel like im missing something big because i have all the prerequisites for this physics course completed and with high grades yet this is our first hw... stuff we should be familiar with.

1. [tex]\int[/tex] 1/(d-x) dx

2. derivative of f(t)= sin([tex]\omega[/tex]t -1)

3. [tex]\int[/tex] x/((x^2)+(L^2))^(3/2) dx

2. Relevant equations

3. The attempt at a solution

I've tried to solve 1 and 3 using trig substitution, partial fractions, integration by parts, u substitution but they all seem to lead to dead ends
