How to solve trigonometric equations easily
WebOct 28, 2024 · To solve it, add 1 to both sides and divide by 3: tan² ( B /2) = 1/3 and then take square root of both sides: tan ( B /2) = ±√ 1/3 = ±√ 3 /3 It’s important to remember to use … WebMar 26, 2016 · A nice, efficient way to solve this equation is to move the 3 to the right and take the square root of each side. Solve for all the possible solutions of 4cos 2 x – 3 = 0 in degrees. Move the number to the right by adding 3 to each side. 4cos 2 x = 3 Divide each side by 4, and then take the square root of each side to solve for cos x.
