First write the whole number as fraction and simply place the whole number in order one

And then multiply the numbers of two fractions and multiply the denominators of the two numbers and then you have to simplify....

Multiplying fractions by whole numbers:
1. You have to convert the whole number into an improper fraction.
2. You then multiply the fractions straight across.
Ex: 2/3 × 6 =2/3 × 6/1 = 2×6/3×1= 12/3= 4

Answer:

Step-by-step explanation:

p(x)=sin(x) is an odd function since sin(-x)=-sin(x).

q(x)=cos(x) is an even function since cos(-x)=cos(x).

r(x)=tan(x) is an odd function since tan(-x)=-tan(x).

s(x)=csc(x) is an odd function since csc(-x)=-csc(x).

So the only contender seems to be C.

Let's check. To check we have to plug in (-x) in place of (x) and see if we get the same function back since we are looking for an even function.

$f(x)=\cos(\frac{5\pi}{4}x)$
