WebSep 7, 2024 · To find the equation of the tangent line, we need a point and a slope at that point. To find the point, compute f( π 4) = cot π 4 = 1. Thus the tangent line passes through the point ( π 4, 1). Next, find the slope by finding the derivative of f(x) = cotx and evaluating it at π 4: f′ (x) = − csc2x and f′ ( π 4) = − csc2( π 4) = − 2.

WebTan(a-b) identity is one of the trigonometry identities for compound angles. It is applied when the angle for which the value of the tangent function is to be calculated is given in the form of the difference of any two angles.The angle (a-b) in the formula of tan(a-b) represents the compound angle. WebInverse trigonometric functions are usually accompanied by the prefix - arc. Mathematically, we represent arctan or the inverse tangent function as tan-1 x or arctan(x). As there are a total of six trigonometric functions, similarly, there are 6 inverse trigonometric functions, namely, sin-1 x, cos-1 x, tan-1 x, cosec-1 x, sec-1 x, and cot-1 x. dr bockrath dentist waynesville
