Applying the series expansion formula for the logarithm, but now we use it to contract the expression, we arrive at $$\int_0^{2\pi}\ln(s^2x^2+1)\;{\rm d}s=\boxed{2\pi\ln(4\pi^2x^2+1)+\frac2x\tan^{-1}(2\pi x)-4\pi}$$ Which is exactly what @Quanto got. Share ...
in general, we can find the slope by using the slope formula. but what if we are given to find an area of a curve? for a curve, the slope of the points varies, and it is then we need differential calculus to find the slope of a curve. you must be familiar with finding out the...
in mathematics, integration by parts is a special method of integration when two functions are multiplied together. this method is used when the integrals are difficult to evaluate. in this method, the integration by parts formula moves the product out of the equation, so that the integral can...
