For v = − 3 ( r − 3 ) when r = − 1 , what does v equal?

Gelneren [198K]

Answer:

Step-by-step explanation:

v = 3 (r - 1)

v = 3(- 1 - 3) <----- Here we are substituting R

v = -3 - 9 <---- Here we expanded the bracket

v = -12 <--- This is your answer, because -3 -9 is equal to -12

4. Find the derivative of sin x from first principle.

olga_2 [115]

Step-by-step explanation:

$\text{By First Principle,}$

$\begin{align}\dfrac{d}{dx}\sin x&=\lim_{h\to0}\frac{\sin(x+h)-\sin x}{h}\\&=\lim_{h\to0}\frac{\sin x\cos h+\sin h\cos x-\sin x}{h}\\&=\lim_{h\to0}\left(\frac{\cos h-1}{h}\cdot\sin x\right)+\lim_{h\to0}\left(\frac{\sin h}{h}\cdot\cos x\right)\\&=\sin x\cdot\left(\lim_{h\to0}\frac{\cos h-1}{h}\right)+\cos x\cdot\lim_{h\to0}\left(\frac{\sin h}{h}\right)\\&=\sin x\cdot 0+\cos x\cdot1\\&=\cos x\end{align}$

$\color{blue}\text{Note: This proof is in fact circular without the geometric proof of the value of the two limits, but for the sake of this question it is done in this way.}$
