Learn how to solve weierstrass substitution problems step by step online. Find the integral int((30t^9)/(1-sin(t^10)))dt. Take out the constant 30 from the integral. We can solve the integral \int\frac{t^9}{1-\sin\left(t^{10}\right)}dt by applying integration by substitution method (also called U-Substitution). First, we must identify a section within the integral with a new variable (let's call it u), which when substituted makes the integral easier. We see that t^{10} it's a good candidate for substitution. Let's define a variable u and assign it to the choosen part. Now, in order to rewrite dt in terms of du, we need to find the derivative of u. We need to calculate du, we can do that by finding the derivative of the equation above. Isolate dt in the previous equation.
