Suppose f is an exponential function and:

Nastasia [14]

Answer: a) $b= p(1 + r)^1$ b) $c= p(1 + r)^n$ c) $d= p(1 + r)^m$ d) $b^n=c$

Step-by-step explanation:

Since f is an exponential function.

So, it is expressed as

$f = p(1 + r)^$

Here f is the present value

p is the initial value

r is the rate of growth per time period

t is the time period.

(a) b represents the 1-unit growth factor for f.

$b= p(1 + r)^1$

(b) c represents the n n-unit growth factor for f.

$c= p(1 + r)^n$

$d= p(1 + r)^m$

Write a formula that expresses c in terms of b.

Since

$b=p(1+r)^1\\\\So,\\\\b=p(1+r)^{n\times \frac{1}{n}}\\\\b=(p(1+r)^n)^{\frac{1}{n}}\\\\b=c^{\frac{1}{n}}\\\\b^n=c$

Hence, a) $b= p(1 + r)^1$ b) $c= p(1 + r)^n$ c) $d= p(1 + r)^m$ d) $b^n=c$

Sine of x divided by one minus cosine of x + sine of x divided by one minus cosine of x = 2 csc x

kolbaska11 [484]

Answer:

The answer in the procedure

Step-by-step explanation:

we have

$\frac{sin(x)}{1-cos(x)}+\frac{sin(x)}{1-cos(x)}=2csc(x)$

Prove the identity

In this problem there is a mistake: in order to obtain an identity the second denominator at the left side must be 1 + cosx

$\frac{sin(x)}{1-cos(x)}+\frac{sin(x)}{1+cos(x)}=2csc(x)$

Adds fraction in the left side

$\frac{sin(x)(1+cos(x)+sin(x)(1-cos(x)}{1-cos^{2} (x)}=2csc(x)\\ \\\frac{2sin(x)}{1-cos^{2} (x)}=2csc(x)$

Remember that

$csc(x)=\frac{1}{sin(x)}$

and

$sin^{2}(x)+cos^{2}(x)=1$

$sin^{2}(x)=1-cos^{2}(x)$

substitute

$\frac{2sin(x)}{sin^{2}(x)}=2\frac{1}{sin(x)}$

Multiply both sides by sin(x)

$(sin(x))\frac{2sin(x)}{sin^{2}(x)}=2$

$\frac{2sin^{2}(x)}{sin^{2}(x)}=2$

$2=2$ ----> identity verified
