WebJan 21, 2024 · In this video lesson we will discover how to Solve Trigonometric Equations using Inverses. In our previous lesson, we learned all the tricks and techniques for solving all types of trigonometric equations using the Unit Circle. WebMar 26, 2016 · Use the reciprocal identity and reciprocal of the number to find the secant. Call the unknown angle θ and rewrite the expression in terms of the cosine of θ with that measure. Write the expression this way in order to change from an inverse trig function to a trig function so you can use the identity. Use the Pythagorean identity to solve for ... WebNov 17, 2024 · All we need to do is look at a unit circle. So, in this case we’re after an angle between 0 and π π for which cosine will take on the value − √ 3 2 − 3 2. So, check out the following unit circle. From this we can see that. cos − 1 ( − √ 3 2) = 5 π 6 cos − 1 ( − 3 2) = 5 π 6. sin−1(−1 2) sin − 1 ( − 1 2) Show Solution. smart grid stocks to watch
