Here, we must first rearrange our equation so all x terms are on one side and all y terms are on the other. Multiplying both sides by dx and diving both by y^(1/2) gives us y^(-1/2)dy = sin(x/2)dx, which is ...

For this, we use the FOIL method of expanding brackets; start by multiplying the FIRST terms of each bracket together to get x x=x^2. Next multiply the OUTSIDE elements, ie the first element in the first bra...

To answer, we must be familiar with several trigonometric identities and expressions; first notice that tan(x)=sin(x)/cos(x). Now our function is a quotient of two functions of x that we can easily different...
