**For Trigonometry, you must be able to**:

·Prove sin²x + cos²x = 1 (using Pythagoras' Theorem and a Unit Circle),

·Prove and Apply the Law of Sines and Cosines

·Apply

a)Half & Double-Angle Formulae: sin2x, cos2x, tan2x, sin ½ x, cos ½ x, tan ½ x

b)Addition-Subtraction Formulae: sin (x ± y), cos (x ± y), tan (x ± y)

c)(IF YOU HAVE TIME TO SPARE) Product-to-Sum and Sum-to-Product Formulae: sin x sin y, cos x cos y, sin x cos y, cos x sin y, sin x ± sin y, cos x ± cos y

·(IF YOU HAVE TIME TO SPARE) Prove of a)-c) above!

·Calculate trigonometric ratios of angles in degrees & radians (usually embedded into another Q)

·Solve fairly sophisticated trigonometric equations: involving preliminary factoring/ trigonometric or algebraic simplification/ use of quadratic formula, etc.

·Graph fairly sophisticated trigonometric functions of form y = A sin (Bx + C) + D, y = A cos (Bx + C) + D, y = A tan (Bx + C) + D or of their reciprocals (cosec, sec, cot: simply flip the base graphs!)

·Prove trigonometric identities: prove Left Hand Side = Right Hand Side

·Prove and Apply Demoivre's Theorem and Finding roots of complex #

·Use elementary trigonometry to find Areas and Perimeters of regular n-sided polygons (48-sided, 64-sided, etc.) or coordinates of vertices of polygons in the coordinate plane

**For Calculus, you must be able to**

·Calculate fairly sophisticated Algebraic and Trig. Limits: esp. those involving factorization/rationalizing the denominator/L'Hospital's Rule for 0/0, infinity/infinity and their variations)

·Define the Definite Integral (Sum of areas) and Calculate Definite Integral using Riemann Sums

·Apply Properties, Areas, Mean Value Theorem with respect to Definite Integrals

·Prove the Fundamental Theorem of Integral Calculus
