- 1Summary of Sine, Cosine, and Tangent angles and values
- 2The properties of the function cosxPeriodic property: cos(x-360) = cosx
Even/odd property: cos(-x) = cosx
Translation property: cos(x-180) = -cosx
Supplementary property: cos(180-x) = -cosx - 3The properties of the function of sinxPeriodic property: sin(x-360) = sinx
Even/odd property: sin(-x) = -sinx
Translation property: sin(x-180) = -sinx
Supplementary property: sin(180-x) = sinx - 4The properties of the function tanxPeriodic property: tan(x-180) = tanx
Odd property: tan(-x) = -tanx
Supplementary property: tan(180-x) = -tanx - 5Solving the equation cosx = kStep 1: Find cos-1(k)
Step 2: Use the symmetry property cos(-x) = cosx to find another root
Step 3: Add or subtract multiples of 360 to find the roots in the required interval - 6Solving the equation sinx = kStep 1: Find sin-1(k)
Step 2: Use the symmetry property sin(180-x) = sinx to find another root
Step 3: Add or subtract multiples of 360 to find the roots in the required interval - 7Solving the equation tanx = kStep 1: Find tan-1k
Step 2: Add or subtract multiples of 180 to find the roots in the required interval - 8Relations between the trigonometric function. Sometimes called Pythagoras' theorem in trigonometry.For all values of x:
tanx = sinx/cosx, provided that cosx does not equal 0;
cos^2(x) + sin^2(x) = 1
