Okay, So if we rewrite the identical integral and then you see, I didn't see that one over coz I is equal to the seacat 50 We can get the integral off seek end squared of t t t divided by the square root of one plus the tangent of tea So we're gonna let you is equal to one plus the tangent of teeth so that D u is equal to see Ken squared of t t t. So we end with Theo integral of you to the power of negative 1/2 to you which is just equal to you to the power off 1/2 multiplied by two, which is two times the square root of you plus c back substituting who is equal to one plus the tangent if t we end up with two times the square root of one plus the tangent of tea plus seat
