Trigonometric complementary relations
WebApr 10, 2015 · For acute angles we can picture this relationship inside a right-angled triangle. The two angles $\theta$ and $\phi$ are complementary, i.e. sum to a right angle, since the angles in a triangle must sum to two right angles.But depending on which angle we choose as our angle of interest, what side counts as "adjacent" and which as "opposite" … WebThe inverse trigonometric functions of reciprocal and complementary functions are similar to the basic trigonometric functions. The reciprocal relationship of the basic trigonometric functions, sine-cosecant, cos-secant, tangent-cotangent, can be interpreted for the inverse trigonometric functions.
