Maths Trignometric Ratios

Sinnπ

The value of sin(π) is 0, as the sine function evaluates to 0 at integer multiples of π.

Cos2nπ

The value of cos(2nπ) is 1, as the cosine function evaluates to 1 at integer multiples of 2π.

Cos(2n+1)π

The value of cos((2n+1)π) is -1, as the cosine function evaluates to -1 at odd integer multiples of π.

Tannπ

The value of tan(π) is 0, as the tangent function evaluates to 0 at integer multiples of π.

Sin(2n+1)π/2

The value of sin((2n+1)π/2) is -1 for odd integers n, as the sine function evaluates to -1 at odd multiples of π/2. For even values of n the value is 1.

Cos(2n+1)π/2

The value of cos((2n+1)π/2) is 0 for all integers n, as the cosine function evaluates to 0 at odd multiples of π/2.

Tan(2n+1)π/2

The value of tan((2n+1)π/2) is undefined for all integers n, as the tangent function is undefined at odd multiples of π/2.
