Trigonometry is thought to have been originally developed in the 1st century B.C.E. to understand astronomy, the study of stars and the solar system. It is still used in space exploration by the likes of NASA and private space transport companies. Frequently Answered Questions What is 2Ï€...
It is a math and trigonometry function available in Microsoft Excel. The MMULT function multiplies two arrays and returns another matrix array. Here’s an overview of its basic use. MMULT Function in Excel: Syntax Function Objective: The MMULT function multiplies two arrays of numbers and ...
The SORT function can sort a multi-column cell range, however, you can only choose one column to sort by. Use the SORTBY function if you need to sort by two or more columns. Formula in cell E3: =SORT(B3:C7, 2) SORT(array, [sort_index], [sort_order], [by_col]) ...

Using a Graphing Calculator to Solve a Trigonometric Equation: Example Problem 1 Use a graphing calculator to solve {eq}4\sin^2(x) - 1 = 2\cos(x)+ 3 {/eq} for {eq}0\leq x < 2\pi {/eq}. Round to three decimal places. Step 1: Make sure your calculator is in the...
Try geometry before trigonometry. While you can use trig to find every side and angle, geometry is usually quicker and easier. First, remember the sum of the angles of any triangle is always 180 degrees. If you know 2 angles of a triangle, you can always subtract their sum from 180 to...
