Simplify using trigonometric identities 2sinθ - sin2θ cosθ

Anit [1.1K]

Double angle identity for sine:

$\sin(2x) = 2 \sin(x) \cos(x)$

$\implies 2 \sin(\theta) - \sin(2\theta) \cos(\theta) = 2 \sin(\theta) - 2 \sin(\theta) \cos^2(\theta)$

Factorize the left side.

$2 \sin(\theta) - 2 \sin(\theta) \cos^2(\theta) = 2 \sin(\theta) \left(1 - \cos^2(\theta)\right)$

Pythagorean identity:

$\cos^2(x) + \sin^2(x) = 1$

$\implies 2 \sin(\theta) \left(1 - \cos^2(\theta)\right) = 2 \sin^3(\theta)$

so that

$\boxed{2 \sin(\theta) - \sin(2\theta) \cos(\theta) = 2 \sin^3(\theta)}$

The city of Anville is currently home to 16000 people, and the population has been growing at a continuous rate of 4% per year.

Nesterboy [21]

Answer

After 13.15 years the population of both towns will become equal.

Step-by-step explanation:

Population of the city Anville is given by using the compound interest formula

The formula of compound interest

A = p( 1+r/n)^n*t

using this we get

P1 = 16000 (1 + $\frac{0.04}{1}$ ) ^1*t

Population of the city of Brinker will be

P2 = 11000( 1 + $\frac{0.07}{1}$ ) ^1*t

now to make equal population in both towns

P1=P2

16000 (1 + $\frac{0.04}{1}$ ) ^1*t = 11000( 1 + $\frac{0.07}{1}$ ) ^1*t

$(\frac{1.04}{1.07} )^t = \frac{11}{16}$

t = 13.15 years
