WebUse a calculator to solve the equation sinθ = 0.8, where θ is in radians. Show Solution Example 5: Using a Calculator to Solve a Trigonometric Equation Involving Secant Use a calculator to solve the equation secθ = − 4, giving your answer in radians. Show Solution Try It Solve cosθ = − 0.2. Show Solution Try It WebSin is equal to the side opposite the angle that you are conducting the functions on over the hypotenuse which is the longest side in the triangle. Cos is adjacent over hypotenuse. And tan is opposite over adjacent, which means tan is sin/cos. this can be proved with some basic algebra. ( 5 votes) Show more... Hidden a year ago

Solving Trigonometric Equations With Identities Precalculus
WebUse a calculator to solve the equation \(\sin \theta=0.8\),where \(\theta\) is in radians. Solution. Make sure mode is set to radians. To find \(\theta\), use the inverse sine … WebMar 22, 2016 · (1) Write this as sin θ − sin ( 99 π / 5) = 0, and factor LHS to give 2 cos 1 2 ( θ + 99 π / 5) sin 1 2 ( θ − 99 π / 5) = 0. Thus you have two possible equations of the form cos a = 0 and sin b = 0. These have the solutions a = ( 1 + 2 j) π and π respectively, where are arbitrary integers. WebOct 17, 2024 · In order to solve this you need to look at inverse trigonometric functions: To solve for θ in general: sin ( θ) = y ⇒ θ = sin − 1 ( y) For your example: g x v 2 = sin ( 2 θ) Thus: 2 θ = sin − 1 ( g x v 2) So: θ = 1 2 sin − 1 ( g x v 2) solly the caterer menu
