What is the arctangent of 1 ? arctan 1 = ? The arctangent is the inverse tangent function. Since tan π/4 = tan 45º = 1 The arctangent of 1 is equal to the inverse tangent function of 1, which is equal to π/4 radians or 45 degrees: arctan 1 = tan-1 1 = π/4 rad ...
Thus, the equation of the unit circle on an x-y plane is $x^2 + y^2 = 1$. Finding Trigonometric Functions Using a Unit Circle We can find trigonometric ratios using the unit circle. Consider the right triangle constructed in the unit circle shown in the diagram below. ...
Equation 2 shows the relationship. We happened to choose a particularly common offset of 90°. The phase offset between a sine and cosine wave is 90°. When there are two sine waves displayed, for example, on a scope, the phase angle can be calculated by measuring the time between the ...
The phase shift between the sine and cosine functions is precisely 90 degrees, meaning that sine can be thought of as a cosine wave shifted 90 degrees to the right, and vice versa. This property is used in analyzing waves and oscillations, where the phase difference can have physical signific...
