The x-intercepts of tan x are where sin x takes the value zero, that is, when x = nπ, where n is an integer. Under that assumption you can argue as @ShlokJain comment suggests, and the fact that $\sin x$ and $\cos x$ must have the same sign, you can discard the condition $\sin x + \cos x =0$. Spinning …

If any individual factor on the left side of the equation is equal to 0 0, the entire expression will be equal to 0 0. We know this from the definition of inverse functions. Underneath the calculator, the six most popular trig functions will appear - three basic ones: sine, cosine, and tangent, and their reciprocals: cosecant, secant, and cotangent.. Multiply sin(x) cos(x) sin(x) sin ( x) cos ( x) sin ( x). Sine, tangent, cotangent, and cosecant are odd functions while cosine and secant are even functions. en. Consequently, for values of h very close to 0, f ′ (x) ≈ f ( x + h) − f ( x) h. Important Notes on Tangent Function: The tangent function is expressed as tan x = sin x/cos x and tan x = Perpendicular/Base; The slope of a straight line is the tangent of the angle made by the line with the positive x-axis
