WebbAs the other answer says, you simply can't express all values of trigonometric functions as fractions. I am guessing that on your TI-84, if you set the calculator to give you the fractions, then sin ( 30 ∘) = sin ( π / 6) will give you 1 2 (that is how it works on my TI-84). But you also know that, for example, sin ( 45 ∘) = sin ( π / 4 ... WebbThe values of trigonometric numbers can be derived through a combination of methods. The values of sine and cosine of 30, 45, and 60 degrees are derived by analysis of the 30-60-90 and 90-45-45 triangles. If the angle is expressed in radians as , this takes care of the case where a is 1 and b is 2, 3, 4, or 6.

Webb13 mars 2024 · To solve, isolate the sine of the unknown angle by multiplying both sides of the equation by the length of angle theta's opposite side. For example: sin A/a = sin B/b becomes (b * sin A)/a = sin B In a calculator, given side a = 5, side b = 7, and angle A = 45 degrees, this is seen as SIN^-1 ( (7*SIN (45))/5). Webb1 dec. 2015 · The cosine is easier: co sine = co mplement's sine, so cosθ = sin(90 ∘ − θ). The point is that you can just read off the trig functions of 45 ∘ from the 45 ∘ - 45 ∘ - 90 ∘ triangle: sin45 ∘ = 1 / √2, cos45 ∘ = sin(90 ∘ − 45 ∘) = sin45 ∘ = 1 / √2, and tan45 ∘ = sin45 ∘ / cos45 ∘ = (1 / √2) / (1 / √2) = 1. crystal midby

Explanation As here too, an odd coefficient of 90° is present, so tan changes to the cot, and also it’s coming to be in the second quadrant where only sine and cosine are positive and rest all are negative. Hence the result of tan 135° = – cot 45° = -1.
