Chain rule:
if
y=y(u) and u=u(x)
The dy/dx=(dv/du)(du/dx)

In our case
y=arcsin(u)
u=sin(x)

dy/du=1/√(1-u²) = 1/√(1-sin²x)
du/dx=cos x

dy/dx=cos x /√(1-sin²x)

Answer: dy/dx=cos x /√(1-sin²x)

Gre4nikov [31]
Make them all decimals or all fractions with the same denominator and it will be easy to tell by inspection which is least.

43/50= .86
.91=.91
7/8= .875
84%=.84

84%. 43/50. 7/8. .91

Estimate the product of<br> 5<br> and 4<br> Then find the product.
Nana76 [90]

1: Look at the 4, its a lot easier to multiply 5 x 5 rather than 5 x 4, plus if you are estimating, you are going to round either up or down.

2: Multiply 5 x 5 // the answer is 25.

3: Multiply 5 x 4 (the original) // which is 20.
