WebYour last sentence is correct. The cos⁻¹(x) is the inverse function to cosine(x). You could say it "undoes" the cosine function, so whereas cosine takes an angle and returns a ratio, cos⁻¹ takes a ratio and returns an angle. You could regard what Sal did as taking cos⁻¹ of both sides, so we'd have cos⁻¹(cos(θ)) = cos⁻¹((19/20) WebSolve your math problems using our free math solver with step-by-step solutions.
