Find cos 50°

WebSince sine function is positive in the first quadrant, thus sin 50° value = 0.7660444. . . Since the sine function is a periodic function, we can represent sin 50° as, sin 50 degrees = sin (50° + n × 360°), n ∈ Z. ⇒ sin 50° = sin 410° = sin 770°, and so on. Note: Since, sine is an odd function, the value of sin (-50°) = -sin (50°). WebSep 28, 2024 · tan 135° = tan (90° + 45°) = tan ( (1 × 90°) + 45°) = -cot 45° = -1. 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.

WebFeb 6, 2024 · A calculus-based solution: As you noticed, we only need to prove that $ \cos 50^{\circ}>\frac{3-\sqrt 3}{2}$.. Because of the identity $\cos 3x=4\cos^3x -3\cos x $, we conclude that $\cos 50^{\circ}$ is a root of the equation: $$\cos 150 ^{\circ}=\frac{-\sqrt 3}{2}=4t^3-3t.$$ However, it is very easy to see that $4t^3-3t+\frac{\sqrt 3}{2}=0$ has … Web2 days ago · The inverse hyperbolic cosine of 3.14 is 1.25. In this example, we first define the value of x as 3.14. We then calculate the value of y using the formula 1 / sqrt (x^2 - 1). Finally, we calculate the inverse hyperbolic cosine of x using the formula ln (x + y) and store the result in the variable result.

WebYou could rearrange the concept a bit to get that the sum of the arguments must be 90 degrees for the sides to be equal, since the sine is the same as the cosine of the complementary angle. We can then set up an equation with just the arguments: 50 - x + 3x + 10 = 90. 2x + 60 = 90. 2x = 30. x = 15. 3 comments. WebThe three main functions in trigonometry are Sine, Cosine and Tangent. They are just the length of one side divided by another. For a right triangle with an angle θ : Sine Function: sin (θ) = Opposite / Hypotenuse. Cosine Function: cos (θ) = Adjacent / Hypotenuse. Tangent Function: tan (θ) = Opposite / Adjacent.
