Prove the trigonometric identity

Annette [7]

Answer:

Proved See below

Step-by-step explanation:

Man this one is a world of its own :D Just a quick question are you a fellow Add Math student in O levels i remember this question from back in the day :D Anyhow Lets get started

For this question we need to know the following identities:

$1+tan^{2}x=sec^2x\\\\1+cot^2x=cosec^2x\\\\sin^2x+cos^2x=1$

Lets solve the bottom most part first:

$1-\frac{1}{1-sec^2x} \\\\$

Take LCM

$1-\frac{1}{1-sec^2x} \\\\\frac{1-sec^2x-1}{1-sec^2x} \\\\\frac{-sec^2x}{1-sec^2x} \\\\\frac{-(1+tan^2x)}{-tan^2x}$

now break the LCM

$\frac{-1}{-tan^2x}+\frac{-tan^2x}{-tan^2x}\\\\\frac{1}{tan^2x}+1\\\\cot^2x+1$

because 1/tan = cot x

and furthermore,

$cot^2x+1\\cosec^2x$

now we solve the above part and replace the bottom most part that we solved with $cosec^2x$

$\frac{1}{1-\frac{1}{cosec^2x} } \\\\\frac{1}{1-sin^2x} \\\\\frac{1}{cos^2x}\\\\sec^2x$

Hence proved! :D

The area of a rectangle is square units. Factor this expression. Given your answer in part A, describe what you can conclude abo

Brrunno [24]

Answer:

The factored area of the rectangle=2(2w-5)

Area of a rectangle=length×width

Step-by-step explanation:

Area of rectangle is 4w - 10 square units

We have to factor the expression

Area of rectangle = 4w - 10

common factor=2

Area of rectangle = 2(2w - 5)

Thus the given expression is factored

Area of a rectangle=length × width

Area of the rectangle=2×(2w-5)

Thus, it is safe to say

The length=2 or (2w-5)

The width=(2w-5) or 2

The answers x^1 or x^0<br> How??

pickupchik [31]

Remember a^(m) x a^(n) = a(m+n) & √a = a^(1/2)

===> x^(1/2 -3/2)+x(1/2 -1/2) ====> x^(-1)+x^(0) (any number Exp 0 =1)
X^(-1) +1 ===> 1/x +1 or (1+x)/x

What is the 60th term of the sequence 2, -3, -8, -13?

aleksandrvk [35]

Answer:

-293

Step-by-step explanation:

The first term of the arithmetic sequence is a1 = 2. The common difference is d = -3-2 = -5. The general term is ...

an = a1 +d(n -1)

an = 2 -5(n -1)

The 60th term is ...

a60 = 2 -5(60 -1) = -293

The population parameters that describe the y-intercept and slope of the line relating y and x, respectively, are _____. a. a an

adelina 88 [10]

The population parameters that describe the y-intercept and slope of the line relating y and x are β₀ and β₁ respectively.

<h3>What is a population model?</h3>

A population model can be represented by the equation:

$\mu_y=\beta_1x + \beta_o$

Where μy is the population mean, β₀ is the y intercept and β₁ is the slope of the line

The population parameters that describe the y-intercept and slope of the line relating y and x are β₀ and β₁ respectively.
