Description
This small set of 18 cards provides a quick reference of basic trigonometric information for the math student. Each card (but one) shows an angle with its degree and radian value, its location on the unit circle, the reference angle, and the sin, cos, and tan value of the angle.
The mnemonic "All Students Take Calculus" is represented behind the unit circle with the letters A, S, T, and C to remind students which quadrant specific trig values are positive.
The eighteenth card provides fundamental trigonometric identities. Given are the basic reciprocal identities, the ratio identities, and the pythagorean identity.
The face of the card provides as a reference the two special right triangles (30-60-90 and 45-45-90) and the relationship of each of the sides.
