sin θ = 1/ cosec θ or sin θ x cosec θ = 1 cos θ = 1/ sec θ or cos θ x sec θ = 1; tan θ = 1/cot θ or tan θ x cot θ = 1; Quotient Relations. Again, as the name suggests, quotient relations involve three trigonometric ratios; where one is the quotient obtained after division operation between the other two. For example, tan θ = sin θ Any triangle whose sides are in the ratio 3:4:5 is a right triangle. Such triangles that have their sides in the ratio of whole numbers are called Pythagorean Triples. There are an infinite number of them, and this is just the smallest. cscθ = 1 sinθ = 5 3. cosθ = AB AC = 4 5. secθ = 1 cosθ = 5 4. tanθ = BC AB = 3 4. cotθ = 1 tanθ = 4 3. Cos A + Cos B formula can be applied to represent the sum of cosine of angles A and B in the product form of cosine of (A + B) and cosine of (A - B), using the formula, Cos A + Cos B = 2 cos ½ (A + B) cos ½ (A - B). Explore. math program. The trigonometric identity Cos A + Cos B is used to represent the sum of sine of angles A and B, Cos A cosecant, secant and tangent are the reciprocals of sine, cosine and tangent. sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the angle θ for which sinθ is a particular value. For example, sin30 = 1/2. sin-1 (1/2) = 30. For more explanation, check this out.

The major functions used in trigonometry are each abbreviated with three letters. The table below shows the primary trigonometric functions and their abbreviations. The angles that they're picking are ones that can be made by adding angles that are easy to remember, namely pi/6, pi/4, pi/3, and pi/2 (30, 45, 60, and 90, respectively) and their multiples. You can use angle addition to quickly find the trig values of, say, 75 degrees, since it's easy to see that 45+30=75. Sine, cosine, and tangent can be used to solve for missing sides if at least one side and one acute angle in a right triangle are known. The function used is determined by the information given These functions give the obvious trigonometric functions. They respectively compute the cosine, sine, tangent, arc-cosine, arc-sine, arc-tangent, and the two-argument arc-tangent. cospi(x), sinpi(x), and tanpi(x), compute cos(pi*x), sin(pi*x), and tan(pi*x). Usage cos(x) sin(x) tan(x) acos(x) asin(x) atan(x) atan2(y, x) cospi(x) sinpi(x) tanpi(x) Now we will divide sin x by cos x. (sin x) / (cos x) = [ (opposite) / (hypotenuse) ] / [ (adjacent) / (hypotenuse) ] = (opposite) / (adjacent) = tan x. Thus, the tangent formula in terms of sine and cosine is, tan x = (sin x) / (cos x) Tangent Formulas Using Pythagorean Identity.
