These variations are detailed at.
Arctangent comes in handy in this situation, as the length of the hypotenuse is not needed.

The following table shows how inverse trigonometric functions may be used to solve equalities involving the six standard trigonometric functions.
Thus in the , "the arc whose cosine is x" is the same as "the angle whose cosine is x", because the length of the arc of the circle in radii is the same as the measurement of the angle in radians.
RHS are both true, or else b the left hand side and right hand side are both false; there is no option c e.
Equation Solution Expanded form of solution where.
Specifically, they are the inverses of the , , , , , and functions, and are used to obtain an angle from any of the angle's trigonometric ratios.
