Solving inverse trig functions
WebAug 20, 2024 · I’m a student currently doing my A levels. While finding solutions for the inverse trig function equation in attachment 1, I came to the step involving a 4-term equation of degree 3(attachment 2). Though I’m familiar with quadratic and 3-term equations of degree 3, I don’t know how to solve this. WebInverse Trigonometric Functions: •The domains of the trigonometric functions are restricted so that they become one-to-one and their inverse can be determined. •Since the definition of an inverse function says that -f 1(x)=y => f(y)=x We have the inverse sine function, -sin 1x=y - π=> sin y=x and π/ 2 <=y<= / 2

Web1. It helps to understand that there are several different functions called cosine. I find it useful to refer to "cos" (the thing for which cos − 1 ( 0) = π / 2) and "cosd" for which cosd (90) = 0. Your calculator (if you're lucky) will mean "cos" when you press the "cos" button; if you've got the option of "degrees/radians", then in ...
