\(\tan\,2 \theta \,\tan\,\theta=1\)
\(\tan3\theta=\frac{\tan\theta+\tan2\theta}{1-\tan\theta.\tan2\theta}\)
\(\tan3\theta=\)∞
i,e, \(3\theta=\frac{2n+1}{2}\pi\)
\(\theta=\frac{{(2n+1)}}{6}\pi\)
The integral \(\int e^x \sqrt{e^x} \, dx\) equals:
The value of : \( \int \frac{x + 1}{x(1 + xe^x)} dx \).
The representation of the area of a region under a curve is called to be as integral. The actual value of an integral can be acquired (approximately) by drawing rectangles.
Also, F(x) is known to be a Newton-Leibnitz integral or antiderivative or primitive of a function f(x) on an interval I.
F'(x) = f(x)
For every value of x = I.
Integral calculus helps to resolve two major types of problems:
