# Trig Facts

### Trigonometry facts to memorize for first term Calculus

csc(x) 1/sin(x)
sec(x) 1/cos(x)
cot(x) 1/tan(x)
1/sin(x) csc(x)
1/cos(x) sec(x)
1/tan(x) cot(x)
y=sin(x) crosses the x-axis where? 0, π and 2π
y=cos(x) crosses the x-axis where? π/2 and 3π/2
y=tan(x) crosses the x-axis where? 0
tan(x) sin(x)/cos(x)
sin(x)/cos(x) tan(x)
cot(x) cos(x)/sin(x)
cos(x)/sin(x) cot(x)
1 cos²(x) + sin²(x)
1 + tan²(x) sec²(x)
sec²(x) 1 + tan²(x)
cos²(x) + sin²(x) 1
cot²(x) + 1 csc²(x)
csc²(x) cot²(x) + 1
sin(A+B) sin(A)cos(B) + cos(A)sin(B)
cos(A+B) cos(A)cos(B) - sin(A)sin(B)
lim sin(x)/x as x->0 1
lim tan(x)/x as x->0 1
lim cos(x)/x as x->0 from the right: ∞ from the left: -∞
lim (1-cos(x))/x as x->0 0
