Trig Year 2 Flashcards
What is the differentiation order for Trig?
Sin –> Cos –> -Sin –> -Cos
What is the intergration order for Trig?
-Cos –> -Sin –> Cos –> Sin
What is the radian measures? (Main values)
2 pi = 360 degrees
pi = 180 degrees
1/2 pi = 90 degrees
3pi/2 = 270 degrees
1 radian = 180/pi
What does Sec equal?
1/cos
What does Cosec equal?
1/sin
What does Cot equal? (2)
1/tan
cos/sin

2nd Year Identities - What is Cosec^2O equal to?
1 + cot^2O
2nd Year Identities - What is Sec^2O equal to?

What is the y=arcsinx graph, the domain and the range?
/ | .
reflected over diagonal
domain = -1 < x < 1
range = - pi/2 < arcsinx < pi/2
or -90 < arcsinx < 90
What is the y=arccosx, the domain and the range?

——-
reflected over diagonal
domain = -1 < x < 1
range = 0 < arccosx < pi
or 0 < arccosx < 180
