Hi Brainiac

1/2 + 2/3

= 3/6 + 4/6

= 7/6

I hope that's help:0

Hello There!

First, find the lowest common denominator. The lowest common denominator is 6 so we will rewrite the equation with the equivalent fractions.

$\frac{3}{6}$ + $\frac{4}{6}$ = $\frac{7}{6}$

$\frac{7}{6}$ = 1 $\frac{1}{6}$

EastWind [94]

From what I can pick up from your problem statement, you want to know "<span>a similar charm has a diameter of 4 cm what is the circumference." Please, would you use proper punctuation in your writing, for greater clarity:

"A</span><span> similar charm has a diameter of 4 cm. What is the circumference?"

The formula for the circumference of a circle, when the diameter is known, is

C=</span> $\pi$ d or C=pi*d

In this case, with diamter 4 cm, the circumference, C, is 4pi cm.

The value of the expression $2\cos(t) + \tan^2(t)$ is 4 and the exact value of $\sin^{-1}(\sin(\frac{5\pi}{3}))$ is $\frac{5\pi}{3}$

<h3>How to determine the trigonometry expression?</h3>

The point on the unit circle is given as:

$P = (\frac 12, \frac{\sqrt{3}}2)$

A point on a unit circle is represented as: (x,y), such that:

cos(t) = x and sin(t) = y.

This means that:

$\cos(t) = \frac 12$

$\sin(t) = \frac{\sqrt 3}{2}$

Calculate tan(t) using:

$\tan(t) = \frac{\sin(t)}{\cos(t)}$

So, we have:

$\tan(t) = \frac{\frac{\sqrt 3}{2}}{1/2}$

Evaluate

$\tan(t) = \sqrt 3$

The expression is then calculated as:

$2\cos(t) + \tan^2(t) = 2 * \frac12 + (\sqrt 3)^2$

Evaluate each term

$2\cos(t) + \tan^2(t) = 1 + 3$

Evaluate the sum

$2\cos(t) + \tan^2(t) = 4$

Hence, the value of the expression $2\cos(t) + \tan^2(t)$ is 4

<h3>How to solve the arcsin expression?</h3>

The expression is given as:

$\sin^{-1}(\sin(\frac{5\pi}{3}))$

As a general rule, the arc sine of sine x is x.

This means that:

$\sin^{-1}(\sin(\frac{5\pi}{3})) = \frac{5\pi}{3}$

Hence, the exact value of $\sin^{-1}(\sin(\frac{5\pi}{3}))$ is $\frac{5\pi}{3}$
