How to calculate trig functions by hand
Web26 mrt. 2016 · You use inverse trigonometry functions to solve equations such as sin x = 1/2, sec x = –2, or tan 2 x = 1. In typical algebra equations, you can solve for the value of x by dividing each side of the equation by the coefficient of the variable or by adding the same thing to each side, and so on. But you can’t do either with the function sin x = 1/2. Web11 apr. 2024 · 🎥 Youtube 🎥 Advanced Topic: Trig Graph Transformations.
