Trig identities

• cos^2x+sin^2x=1
• sec^2x=1+tan^2x
•cosec^2x= 1+cot^2x

2

Sin2A=

2sinAcosA

3

Cos2A

=cos^2A-sin^2A
=2cos^2A-1
=1-2sin^2A

4

Tan2A=

2tanA/1-tan^2A

5

Cosecx

1/sinx

6

Secx

1/cosx

7

Cotx

1/tanx
Cosx/sinx

8

Rotation around x axis

Y^2

9

Rotation around y axis

X^2

10

Differential of A^x

LnA*A^x

11

Differential of lnx

1/x

12

Define divergent

The values just keep getting larger, not closing in on the limit

13

Define convergent

When they keep getting closer and closer and closer to the root

14

Reflection in the x axis

Y=-f(x)

15

Reflection in the y axis

Y=f(-x)
