Show Solution. 3. a2+a2tan2θ a 2 + a 2 tan 2 θ. 4. a2+a2sinh2θ a 2 + a 2 sinh 2 θ. Sine and cosine are the fundamental trigonometric functions arising from the previous diagram:. The sine of theta (sin θ) is the hypotenuse's vertical projection (green line); andThe cosine of theta (cos θ) is the hypotenuse's horizontal projection (blue line).We can rotate the radial line through the four quadrants and obtain the values of the trig …It consists of more than 17000 lines of code. When the integrand matches a known form, it applies fixed rules to solve the integral (e. g. partial fraction decomposition for rational functions, trigonometric substitution for integrands involving the square roots of a quadratic polynomial or integration by parts for products of certain functions). The following indefinite integrals involve all of these well-known trigonometric functions. Some of the following trigonometry identities may be needed. It is assumed that you are familiar with the following rules of differentiation. These lead directly to the following indefinite integrals.
