NettetSo, substituting the two parts we figured out gives us (a^2 * sec^2 (theta)) in the denominator and sec^2 (theta)d (theta) in the numerator. These sec^2 (theta)s can … NettetCalculus. Find the Integral tan (theta)^2. tan2 (θ) tan 2 ( θ) Using the Pythagorean Identity, rewrite tan2(θ) tan 2 ( θ) as −1+sec2 (θ) - 1 + sec 2 ( θ). ∫ −1+sec2(θ)dθ ∫ - 1 + …

NettetIf you have a right triangle with hypotenuse of length a and one side of length x, then: x^2 + y^2 = a^2 <- Pythagorean theorem where x is one side of the right triangle, y is the other side, and a is the hypotenuse. So anytime you have an expression in the form a^2 - x^2, you should think of trig substitution. Now here's where the trig comes in: NettetWhat follows is one way to proceed, assuming you take log to refer to the natural logarithm. Recall that ∫ log(u) du = ulog(u) - u + C, where C is any real number. Using the substitution u = x + 1, du = dx, we may write ∫ log(x + 1) dx = ∫ log(u) du = ulog(u) - u + C.Now we may substitute u = x + 1 back into the last expression to arrive at the answer: gear of 6

NettetFinally we put all the pie wedges together, to get a total of ∫ α β ( ∫ a b f ( r, θ) r d r) d θ. The infinitestimal area in rectangular coordinates is d A = d x d y. The infinitesimal area in polar coordinates is. d A = r d r d θ. Don't forget the factor of r !!
