Web13 feb. 2024 · What Are Sin Cos theta Formula ? If (x,y) is a point on the unit circle, and if a ray from the origin (0, 0) to (x, y) makes an angle θ from the positive axis, then x and y satisfy the Pythagorean theorem x 2 + y 2 = 1, where x and y form the lengths of the legs of the right-angled-triangle. Thus the basic sin cos formula becomes cos 2 θ ...

Web5 aug. 2024 · sinθ - cosθ = 0. To find : The value of θ. Solution : We can simply solve this mathematical problem by using the following mathematical process. Here, we will use … WebIf we write opposite of the value of Sin degrees, we get the values of cos degrees. Because, Sin θ=1/Cos θ. Therefore we can write, Sin 0 0 = Cos 90 0 =0. Sin 30 0 =Cos 60 0 =½. Sin 45 0 =Cos 45 0 = 1/√2. Sin 60 0 =Cos 30 0 = √3/2. Sin 90 0 =Cos 0 0 =1. In the same way, we can write the values for Tan degrees.
