A cosine function is graphed starting at (0,1). Mark the x-axis 90, 180, 270, and 360 for degrees or their values in radians (pi/2, pi, 3pi/2, 2pi). Since sine relates the ratio of x to the radius of the triangle formed on the unit circle, at 90 (pi/2) the value of ...

1. Explain Sine Function. The sine function is one of the most important functions in trigonometry other than cosine and tangent function The sine function is defined as the ratio of the length of the opposite side of the right-angle triangle to its hypotenuse side. For example, a triangle...
Sin 0 Degrees value and other trigonometric ratios are used for common angles like 0°, 30°, 45°, 60°, 90° are used in trigonometric equations and calculations. Name Abbreviation Relation Sine Sin Sin(θ)= Opposite/Hypotenuse CoSine Cos Cos(θ)= Adjacent/Hypotenuse Tangent Tan Tan(θ)=...
Two of the main trigonometric functions are sine and cosine. If a function is the sum of two different functions, we use the linearity. It states that d dx(f(x)+g(x))= d dx(f(x))+ d dx(g(x)) To compute the derivative of a tr...
