### y=4x^t + 5x^-1 + 6sinx.

We'll recall the fundamental Theorem of Calculus:

Int f(x)dx = F(b) - F(a) for x = a to x =b.

Since the limits are not given, we could only calculate the indefinite integral:

Int (4x^t + 5x^-1 + 6sinx)dx

We'll use the additive property of integrals:

Int (4x^t + 5x^-1 + 6sinx)dx = Int 4x^tdx + Int5x^-1dx + Int 6sinxdx

**Int ydx = 4*x^(t+1)/(t+1) + 5 ln|x| - 6cos x + C**
