Sin X = 1 / 2orSin X = -1 The first equation gives two vales (X = 30o, X = 150o), the second equation gives one value (270o). Thus the solution of the original equation is: X = 30o, X = 150oand X = 270o. 2 Cos2X + Sin 2X = 0 Using the double angle identity, t...
There are six hyperbolic functions, namely sinh x, cosh x, tanh, x, coth x, sech x, csch x. A hyperbolic function is defined for a hyperbola. The hyperbolic identities are analogous to trigonometric identities.Related Topicstanh x Hyperbola Hyperbola Calculator...
-sin y (dy/dx) = 1dy/dx = 1/(-sin y) = -1/sin y ... (1)By one of the trigonometric identities, sin2y + cos2y = 1. From this, sin y = √1-cos²y = √1-x².Substituting this in (1),dy/dx = -1/√1-x² (or)...
In summary: So to summarize, in solving trigonometric equations, it is important to remember the trigonometric identities and understand the difference between expressions like sin2x and sin2x, which have different meanings and cannot be used interchangeably. It is also important to understand...
