anonymous one year ago • Provide an example of a trig function and describe how it is transformed from the standard trig function f(x) = sin x, f(x) = cos x, or f(x) = tan x

1. welshfella

an example is the sine and the cosecant

@welshfella im confused

Taking the example of Welshfella, the Cosecant function derives from the reciprocal of the Sine function. That is: $cscx = \frac{ 1 }{ \sin x }$

Why is the interval important when calculating the rate of change on a trig function? @Hoslos

Similarly, the Tangent function derives from the division of sine and cosine: $tanx = \frac{ sinx }{ \cos x }$

6. anonymous

That is crucial, as the result of the trig function might give a zero in the denominator, which will make the function undefined. For instance, given the above formula for Tangent, I cannot include the root 90Degrees, because $\frac{ \sin 90 }{ \cos 90 }=\frac{ 1 }{ 0 }=undefined$ Is that understandable?
