If x= sin theta then x/√1-x^2 is

SCORPION-xisa [38]

Well,

Given that $x=\sin(\theta)$ ,

We can rewrite the equation like,

$\dfrac{\sin(\theta)}{\sqrt{1-\sin(\theta)^2}}$

Now use, $\cos(\theta)^2+\sin(\theta)^2=1$ which implies that $1-\sin(\theta)^2=\cos(\theta)^2$

That means that,

$\dfrac{\sin(\theta)}{\sqrt{1-\sin(\theta)^2}}\Longleftrightarrow\dfrac{\sin(\theta)}{\sqrt{\cos(\theta)^2}}$

By def $\sqrt{x^2}=x$ therefore $\sqrt{\cos(\theta)^2}=\cos(\theta)$

So the fraction now looks like,

$\dfrac{\sin(\theta)}{\cos(\theta)}$

Which is equal to the identity,

$\boxed{\tan(\theta)}=\dfrac{\sin(\theta)}{\cos(\theta)}$

Hope this helps.

A student was asked to add the fractions below. 33 + 1 For their first step the student wrote the problem as 9/24 + 10/24

Tomtit [17]

Answer:

see below

Step-by-step explanation:

a)The least common multiple of 8 and 12 is 24

3*8 =24

2*12 = 24

3/8 * 3/3 =9/24

5/12 * 2/2 = 10/24

9/24 + 10/24 =19/24

8 miles in 40 minutes = 12 miles per hour

5 miles in 30 minutes = 10 miles per hour

workings

60/40=1.5

1.5x8=12

60/30=2

2x5=10

method

you divide the 60 by however many minutes, then times that by the amount of miles
