Given tan = 2 and sin >0, find the values of the other five trig functions. Since sin >0 and tan <0, then cos <0 and is in quadrant II. sin =p2 5 2 p 5 5 cos =p 1 5 p 5 5 cot = 1 2 sec = p 5 csc = p 5 2 1 2 p 5 University of Minnesota Values of tan, cot, sec, csc The value where the function is not defined can be excluded from the domain. The range of a trigonometric function is given by the output values for each of the input values (domain). Also, use the reciprocal identities csc x = 1/sin x, sec x = 1/cos x, and also the identities tan x = sin x/cos x and cot x = cos x/sin x to find the domain and If you are asked to find the sin/cos/tan of an angle it will most likely be the common angles:0,30,45,60,90. 15 and 75 at a push. Learn the values for these. The truth is there's no easy way to compute the tan/sin/cos of an angle without the calculator. The best you could do is use a Maclaurin series. That would involve having to convert from ThePythagoreanIdentity is still true when we use the trigonometric functions of an angle. That is, for any angle, cos(θ)2 + sin(θ)2 = 1. In addition, we still have the inverse trigonometric functions. In particular, θ = arcsin(x) = sin − 1(x) means sin(θ) = x and − π 2 ≤ θ ≤ π 2 or − 90 ∘ ≤ θ ≤ 90 ∘. This function returns the cosine of the value passed (x here). The input x is an angle represented in radians. tan(x) Function. This function returns the tangent of the value passed to it, i.e sine/cosine of an angle. The input here is an angle in terms of radians. Code example for sin, cos, and tan: 6K53u.
