_______________


Let  \mathsf{\theta=sin^{-1}(x)\qquad\qquad-\dfrac{\pi}{2}\ \textless \ \theta\ \textless \ \dfrac{\pi}{2}.}

(that is the range of the inverse sine function).


So,

\mathsf{sin\,\theta=sin\!\left[sin^{-1}(x)\right]}\\\\ \mathsf{sin\,\theta=x\qquad\quad(i)}


Square both sides:

\mathsf{sin^2\,\theta=x^2\qquad\qquad(but~sin^2\,\theta=1-cos^2\,\theta)}\\\\ \mathsf{1-cos^2\,\theta=x^2}\\\\ \mathsf{1-x^2=cos^2\,\theta}\\\\ \mathsf{cos^2\,\theta=1-x^2}


Since \mathsf{-\,\dfrac{\pi}{2}\ \textless \ \theta\ \textless \ \dfrac{\pi}{2},} then \mathsf{cos\,\theta} is positive. So take the positive square root and you get

\mathsf{cos\,\theta=\sqrt{1-x^2}\qquad\quad(ii)}


Then,

\mathsf{tan\,\theta=\dfrac{sin\,\theta}{cos\,\theta}}\\\\\\ \mathsf{tan\,\theta=\dfrac{x}{\sqrt{1-x^2}}}\\\\\\\\ \therefore~~\mathsf{tan\!\left[sin^{-1}(x)\right]=\dfrac{x}{\sqrt{1-x^2}}\qquad\qquad -1\ \textless \ x\ \textless \ 1.}


I hope this helps. =)

1. Label the place value charts. Fill in the blanks to make the following equations true. Draw disks in the
ivanzaharov [21]

[1] (a) 10 times 4 ones = 10 x 4 ones = 40

(b) 10 times 2 tens = 2 tens = 20

(c) 5 times hundred times 10 = 50 hundreds = 50

[2] (a) 10 times as many as 1 hundred is 10 x 100 = 10 hundreds or 1000 x 1 = 1 thousand

(b) 10 times 6 hundreds is 60 hundreds / 6 thousands

(c) 10 times 8 hundreds is 8 thousands.

(d) 40 hundreds is same as 4 thousands.

<h3>What Is Place Value in Math? </h3>

Place value is the base of number system. This is that system in which the position of a digit in a number tells/determine its value. The number 41,316 is different from 51,432 because the digits are in different positions.

The place value of 4 in 41,316 is 10 thousands and place value of 4 in 51,432 is 1 hundred.

we can also find the place value by multiplying the required number of 10.

for ones → multiply by 1

for tens → multiply by 10

for hundreds → multiply by 100

for thousands → multiply by 1000

for ten thousands → multiply by 10000

Here we have given

[1]

(a) 10 times 4 ones which is equal to 40 ones = 40

(b) 10 times 2 tens = 2 tens = 20

(c) 5 hundreds times 10 = 50 hundreds = 50

[2]

(a) 10 times as many as 1 hundred is 10 x 100 = 10 hundreds or 1000 x 1 = 1 thousand

(b) 10 times 6 hundreds is 60 hundreds or 6 thousands

(c) 10 times 8 hundreds is 8 thousands.

(d) 40 hundreds is same as 4 thousands.

Hence,

[1] (a) 10 times 4 ones = 10 x 4 ones = 40

(b) 10 times 2 tens = 2 tens = 20

(c) 5 times hundred times 10 = 50 hundreds = 50

[2] (a) 10 times as many as 1 hundred is 10 x 100 = 10 hundreds or 1000 x 1 = 1 thousand

(b) 10 times 6 hundreds is 60 hundreds or 6 thousands

(c) 10 times 8 hundreds is 8 thousands.

(d) 40 hundreds is same as 4 thousands.
