Evaluate tan(sin^-1(-4/5)). Enter your answer as a fraction using the slash bar (/).

Anvisha [2.4K]

Answer:

-1333/1000

Step-by-step explanation:

Evaluate tan(sin^-1(-4/5)).

First we need to evaluate the expression in parenthesis

sin^-1(-4/5)

= sin^-1(-0.8)

= -53.13

SUbstitute the given value into the original expression as shown;

tan(sin^-1(-4/5))

= tan(-53.13)

= -1.333

= -1333/1000

Hence the required answer is -1333/1000

سا (a) From the definition of derivatives determine dy÷dx if y = -2÷x

harina [27]

Step-by-step explanation:

Given: $y = -\dfrac{2}{x}$

Derivative of a power function $x^n$ :

$\dfrac{d}{dx}(x^n) = nx^{n-1}$

Therefore,
