Replace cos^2(θ) with 1-sin^2(θ), and cot(θ) with cos(θ)/sin(θ).
cos^2(θ)cot^2(θ) = cot^2(θ) - cos^2(θ)
(1 -sin^2(θ))cot^2(θ) = . . . . . replace cos^2 with 1-sin^2
cot^2(θ) -sin^2(θ)·cos^2(θ)/sin^2(θ) = . . . . . replace cot with cos/sin
cot^2(θ) -cos^2(θ) = cot^2(θ) -cos^2(θ) . . . as desired
Answer:
Step-by-step explanation:
We have been given that there are total 9 people who entered the drawing competition. There are 3 prizes to be distributed to the winners. The total number of ways that 3 prizes can be awarded to the 9 people can be determined as 9*8*7 = 504.
The total number of ways in which I win the first prize and my mom wins the second prize would be 1*1*7 = 7.
Therefore, the probability that I win the first prize and my mom wins the second prize would be: 
Answer:

Use a square + b square = c square a and b are the short sides of a triangle and c is the largest side of a triangle.
Answer:
The answer to your question is below
Step-by-step explanation:
To solve this problem, for a and c, just look in the x-axis the value given and find the value of a and c in the y-axis.
To solve this problem, for b and d, just look in the y-axis the value given and find the value of b and d in the x-axis.
f(2) = -3 a = -3
f(b) = 0 b = -4
f(-2) = -1 c = -1
f(d) = -6 d = 8
