T.2.0: Students know the definition of sine and cosine as y- and x-coordinates of points on the unit circle and are familiar with the graphs of the sine and cosine functions.
T.3.1: Students prove that this identity is equivalent to the Pythagorean theorem (i.e., students can prove this identity by using the Pythagorean theorem and, conversely, they can prove the Pythagorean theorem as a consequence of this identity).
T.3.2: Students prove other trigonometric identities and simplify others by using the identity cos²(x) + sin²(x) = 1. For example, students use this identity to prove that sec²(x) = tan²(x) + 1.
T.4.0: Students graph functions of the form f(t) = A sin (Bt + C) or f(t) = A cos (Bt + C) and interpret A, B, and C in terms of amplitude, frequency, period, and phase shift.
T.5.0: Students know the definitions of the tangent and cotangent functions and can graph them.
T.7.0: Students know that the tangent of the angle that a line makes with the x-axis is equal to the slope of the line.
T.9.0: Students compute, by hand, the values of the trigonometric functions and the inverse trigonometric functions at various standard points.
T.10.0: Students demonstrate an understanding of the addition formulas for sines and cosines and their proofs and can use those formulas to prove and/or simplify other trigonometric identities.
T.11.0: Students demonstrate an understanding of half-angle and double-angle formulas for sines and cosines and can use those formulas to prove and/or simplify other trigonometric identities.
T.12.0: Students use trigonometry to determine unknown sides or angles in right triangles.
T.15.0: Students are familiar with polar coordinates. In particular, they can determine polar coordinates of a point given in rectangular coordinates and vice versa.
T.16.0: Students represent equations given in rectangular coordinates in terms of polar coordinates.
T.17.0: Students are familiar with complex numbers. They can represent a complex number in polar form and know how to multiply complex numbers in their polar form.
T.18.0: Students know DeMoivre's theorem and can give nth roots of a complex number given in polar form.
