You can use the identity
cos(x)² +sin(x)² = 1
to find sin(x) from cos(x) or vice versa.
(1/4)² +sin(x)² = 1
sin(x)² = 1 - 1/16
sin(x) = ±(√15)/4
Then the tangent can be computed as the ratio of sine to cosine.
tan(x) = sin(x)/cos(x) = (±(√15)/4)/(1/4)
tan(x) = ±√15
There are two possible answers.
In the first quadrant:
sin(x) = (√15)/4
tan(x) = √15
In the fourth quadrant:
sin(x) = -(√15)/4
tan(x) = -√15
Answer:
It is at 0 that mean that is the answer right?
Step-by-step explanation:
So,
Lets say you have a improper fraction that you want to put into a mixed number.
45
----
7
To put this into a mixed number, you divide the numerator by the denominator and put the remainder back into the numerator
45/7=6 R3
6 3/7 is the mixed number of 45/7.
