Question 1

What is the cosine rule?

Answer 1

Question 2

Area of a triangle

Answer 2

Question 3

What is the graph of Y=sinx

Answer 3

Question 4

What is the graph of y=cosx

Answer 4

Question 5

What is the graph of y=tanx

Answer 5

Question 6

y=f(x) + C

Answer 6

C > 0, moves graph up
C < 0, moves graph down

Question 7

y=f(x+C)

Answer 7

C > 0, moves graph left
C < 0, moves graph right

(x,y) –> (x-c, y)

Question 8

y= -f(x)

Answer 8

reflects graph on x-axis

Question 9

y=f(-x)

Answer 9

Reflects graph in y axis

Question 10

y= Cf(x)

Answer 10

C > 1, stretches the graph in the y-direction (x, cy)

0 < C < 1, Stretches the graph (x/c, y)

Answer 11

An obtuse angle is an angle that measures more than 90 degrees and less than 180 degrees
