Describe the similarities and differences between the percent proportion and the percent equation.
vaieri [72.5K]
Percent proportion is just any positive fraction, which, as it was mentioned, can exceed whether the percentage has a fixed denominator, equal to 100. So, although there's no intuitive difference, there is a slight distinction in the mathematical sense. It is also the amount of items in a mixture. Example: two eggs for every two cups of flour.

percent equation is a part of something equals to percent times the whole
part = percent x whole

Example: what is 80% of 20?

n = 80/100 x 20
n= 0.80 x 20
n = 16
So 16 is 80% of 20
part (16) = percent (80%) x whole (20)
n = p x w (variable representation

Sin\theta +cos\theta =1
Mamont248 [21]

Answer:

θ = 2 π n_1 + π/2 for n_1 element Z  or θ = 2 π n_2 for n_2 element Z

Step-by-step explanation:

Solve for θ:

cos(θ) + sin(θ) = 1

cos(θ) + sin(θ) = sqrt(2) (cos(θ)/sqrt(2) + sin(θ)/sqrt(2)) = sqrt(2) (sin(π/4) cos(θ) + cos(π/4) sin(θ)) = sqrt(2) sin(θ + π/4):

sqrt(2) sin(θ + π/4) = 1

Divide both sides by sqrt(2):

sin(θ + π/4) = 1/sqrt(2)

Take the inverse sine of both sides:

θ + π/4 = 2 π n_1 + (3 π)/4 for n_1 element Z

or θ + π/4 = 2 π n_2 + π/4 for n_2 element Z

Subtract π/4 from both sides:

θ = 2 π n_1 + π/2 for n_1 element Z

or θ + π/4 = 2 π n_2 + π/4 for n_2 element Z

Subtract π/4 from both sides:

Answer: θ = 2 π n_1 + π/2 for n_1 element Z

or θ = 2 π n_2 for n_2 element Z
