All we are left with is rπ.You have to use the combination of product rule and quotient rule for the second term in this expression.......
What is the derivative of rπx+q*sin(w)?
w, q, r are constants. Solve with respect to x.

-
d (r π x+q*sin(w)) / dx =
r π

since +qsinw is a constant not a coefficient of x.

Step 1, split this into two derivatives:

dy/dx rπx+q Since the derivative of a constant is zero, you only need worry about the rπx whose derivative is simply rπ.

dy/dx q*sin(w) You need to use the product rule for this one. f[x] * g'[x] + f'[x] * g[x]

let q be f[x], then f'[x] will be 0 since the derivative of a constant is zero.

let sin(w) be g[x], then g'[x] will need the chain rule, derivative of the outside, leave the inside, times the derivative of the inside. So, g'[x] would be Cos[w]*0 = 0.

Now we need to recombine :

f[x] * g'[x] + f'[x] * g[x]

q * 0 + 0 * sin(w) = 0.

Now we have to recombine the two derivatives from the beginning:

All we are left with is rπ.

-
dy/dx = x + [ q * cos(w) * w]

You have to use the combination of product rule and quotient rule for the second term in this expression.

Hope this helps
