sin(x) = 
1 / csc(x)


cos(x) = 
1 / sec(x) 

tan(x) = 
sin(x) / cos(x) 

csc(x) = 
1 / sin(x) 

sec(x) = 
1 / cos(x) 

cot(x) = 
cos(x) / sin(x)


sin^2(x) + cos^2 (x) = 
1 

1  sin^2(x) = 
cos^2(x) 

1  cos^2(x) = 
sin^2(x)


tan^2(x) + 1 = 
sec^2(x) 

cot^2(x) + 1 = 
csc^2(x) 

sin(2x) = 
2sin(x)cos(x) 

cos(2x) = 
cos^2(x)  sin^2(x) 

sin^2(x) = 
[ 1  cos(2x) ] / 2 

cos^2(x) = 
[ 1 + cos(2x) ] / 2 

d/dx sin(x) = 
cos(x)


d/dx cos(x) = 
sin(x) 

d/dx tan(x) = 
sec^2(x) 

d/dx cot(x) = 
csc^2(x)


d/dx sec(x) = 
sec(x) tan(x) 

d/dx csc(x) = 
csc(x) cot(x) 

More later. (maybe. I'm tired)
