The sine function, {eq}f(x) = \sin(x) {/eq}, is one of the six trigonometric functions. The sine maybe defined in terms of other trigonometric functions, for example as {eq}\sin(x )= \frac{1}{\csc(x)} {/eq}, or in the context of the right triangle as {eq}\sin(x ...
One notable relationship between the sine and cosine functions is that, suppose we have {eq}\cos(\theta) {/eq}, a phase shift of {eq}90^{\circ} {/eq} of the angle {eq}\theta {/eq} would give an equivalent sine value. Showing this mathematically, $$\cos(\theta + 90^{\circ})...
In mathematics, the function is classified as an odd and even function. The even function is the function that does not change when it reflects about the y-axis. That implies f(−x)=f(x). The cosine function is one of the even functions. So, it have the property: ...
