Given the point $P(a, b)$ on the unit circle, find the exact values of sine, cosine, and tangent for the angles $ heta$ and $phi$ where $ heta$ is the angle between the positive x-axis and the line segment $OP$ and $phi$ is the angle in radians corres
Answer 1
Given the point $P(a, b)$ on the unit circle, we know that $a^2 + b^2 = 1$.
For angle $\theta$:
The sine and cosine values are the coordinates of point P, so:
$\sin(\theta) = b$
$\cos(\theta) = a$
To find the tangent, we use:
$\tan(\theta) = \frac{\sin(\theta)}{\cos(\theta)} = \frac{b}{a}$
For angle $\phi$:
Since $\phi$ represents the arc length from $(1, 0)$ to $P$, we use the unit circle property that $\phi$ forms the same angle as $\theta$ from the origin:
$\sin(\phi) = b$
$\cos(\phi) = a$
$\tan(\phi) = \frac{\sin(\phi)}{\cos(\phi)} = \frac{b}{a}$
Answer 2
To solve for $ heta$ and $phi$ given $P(a, b)$ on the unit circle, we start with:
$a^2 + b^2 = 1$
For $ heta$:
$sin( heta) = b$
$cos( heta) = a$
$ an( heta) = frac{b}{a}$
For $phi$:
Since $phi$ is the arc length corresponding to the angle $ heta$:
$phi = heta$
So,
$sin(phi) = b$
$cos(phi) = a$
$ an(phi) = frac{b}{a}$
Answer 3
Given $P(a, b)$ on the unit circle,
$a^2 + b^2 = 1$
For $ heta$:
$sin( heta) = b$
$cos( heta) = a$
$ an( heta) = frac{b}{a}$
For $phi$:
$sin(phi) = b$
$cos(phi) = a$
$ an(phi) = frac{b}{a}$
