Derivative of csc(x) = $\frac{d}{dx} [csc(x)] = -csc(x)cot(x)$

Step-by-step explanation:

Step 1: Define

$\frac{d}{dx} [csc(x)]\\x = \frac{3 \pi}{2}$

Step 2: Differentiate

Differentiate: $\frac{d}{dx} [csc(x)] = -csc(x)cot(x)$

Step 3: Evaluate

Substitute in x: $-csc(\frac{3 \pi}{2} )cot(\frac{3 \pi}{2} )$
Evaluate: $0$

If y is 2.5 when x is 5 and i varies directly with x, find y when x is 14 ?

Anestetic [448]

ANSWER

$y = 7$

EXPLANATION

If y varies directly with x, we write the mathematical statement;

$y \propto \: x$

When we introduce the constant of proportionality k, then we write the equation,

$y = kx$

If y is 2.5 when x is 5,then we have;

$2.5 = 5k$

$k = \frac{2.5}{5}$

$k = 0.5$

The equation of variation then becomes;

$y = 0.5x$

when x=14,

$y = 0.5(14)$

$y = 7$
