same purpose of finding an unknown angle. If the length of the adjacent side or base and hypotenuse of a triangle are given then by using the inverse of the cosine function we can easily find the values of the unknown angle. It is represented by Cos-1. And often referred to as Arcos....
In this lesson we will learn how to integrate the expression cos(x) using the fundamental theorem of calculus. We will also look at how derivatives...
Find the exact value of 5^log_5(pi). Find the exact values of the following: 1. cos\frac{7\pi}{6}=? 2. tan\frac{2\pi}{3}=? 3. sin(\frac{7\pi}{6})=? 4. csc(\frac{2\pi}{3})=? Find the exact function value. tan 90 degrees ...
Inverse trigonometric functions are also called arcus functions or anti-trigonometric functions. These are the inverse functions of the trigonometric functions with suitably restricted domains. They are used to obtain an angle from any of the angle's trigonometric ratios. These ...
Using an inverse tangent infinite series, a team led by George Reitwiesner and John von Neumann that same year achieved 2,037 digits with a calculation that took 70 hours of computer time on the ENIAC computer. The record, always relying on an arctan series, was broken repeatedly until 1 ...
