Let’s look at how to use trigonometric identities to calculate missing sides. \({sin~θ} = \frac {opposite} {hypotenuse}\) \({cos~θ} = \frac {adjacent} {hypotenuse ...

This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the \(y ...

tan⁻¹√1+tan2 θ x sin(π-θ))=1-a2/(1+a)2 Q: 4 The domain of f (x) = sin⁻¹x - cos⁻¹x is [-1, 1] while its range is [-3π/2, π/2]. If g (x) is the inverse of f (x), which of the ...
