Determine the primary trigonometric ratios for each angles a) -pi/2
To determine the primary trigonometric ratios for an angle of -π/2, we need to find the values of sine, cosine, and tangent of this angle.
a) For an angle of -π/2:
The sine of -π/2 is equal to -1.
The cosine of -π/2 is equal to 0.
The tangent of -π/2 is undefined.
Therefore, the primary trigonometric ratios for an angle of -π/2 are:
Sine = -1
Cosine = 0
Tangent = undefined.
