*b**a*Trigonometric functions: (also called circular functions, angle functions) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

sinθ = *a**c*

cosθ = *b**c*

tanθ = *a**b*

cscθ = *c**a*

secθ = *c**b*

cotθ = *b**a*

sinθ = cos(*π**2* - θ) = *1**cscθ*

cosθ = sin(*π**2* - θ) = *1**secθ*

tanθ =
*sinθ*
*cosθ*
=
cot(*π**2* - θ)
=
*1**cotθ*

cotθ =
*cosθ*
*sinθ*
=
tan(*π**2* - θ)
=
*1**tanθ*

secθ = csc(*π**2* - θ) = *1**cosθ*

cscθ = sec(*π**2* - θ) = *1**sinθ*

Find the x value of the equation：sin(x)-cos(x)=0

sin(x) - cos(x) = 0

sin(x) = cos(x)

- 2sin(*π**4* - x) = 0

x = *π**4*+kπ , k ∈ Z
