Using chain rule, what is the derivative of sin(arcsin(x))

sergey [27]

Chain rule
y=f(g(x))
y´=(d f(gx)/d g)(d g/d x)

or

y=y(v) and v=v(x), then dy /dx=(dy/dv)(dv/dx)

in our case:
y=sin (v)
v=arcsin(x)

dy/dv=d sin (v)/dv=cos (v)=cos(arcsin(x)
dv/dx=d arcsin(x)/dx=1/√(1-x²)

dy/dx=[cos (arcsin(x))]/√(1-x²)

Answer: d sin(arcsin(x))/dx=[cos (arcsin(x))]/√(1-x²)

The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h. Solve for a

den301095 [7]

Answer:

$a=\frac{2A}{h}-b$

Step-by-step explanation:

we know that

The formula to calculate the area for a trapezoid is equal to

$A=\frac{1}{2}(a+b)h$

where

a and b are the parallel bases

h is the height of trapezoid

A is the area

<em>Solve for a</em>

That means ----> isolate the variable a

Multiply by 2 both sides to remove the fraction in the right side

$2A=(a+b)h$

Divide by h both sides

$\frac{2A}{h}=a+b$

Subtract b both sides

$\frac{2A}{h}-b=a$

Rewrite

$a=\frac{2A}{h}-b$
