 Trigonometry Section 4 Sine(theta) opposite/hypothenuse Cosine(theta) adjacent/Hypothenuse Tangent(theta) opposite/adjacent Cosecant(theta) hypothenuse/opposite Secant(theta) hypothenuse/adjacent Cotangent(theta) adjacent/opposite if t is any real number, what is cos t? cos t = x if t is any real number, what is sin t? sin t = y if t is any real number, what is tan t? tan t = y/x, x cannot equal 0 if t is any real number, what is csc t? csc t = 1/y, y cannot equal 0 if t is any real number, what is sec t? sec t = 1/x, x cannot equal 0 if t is any real number, what is cot t? cot t = x/y, y cannot equal 0 when P(x,y) are the points belonging to t, what are the corresponding trig functions on the unit circle? P(x,y) = (cos t, sin t) What is the relationship between cos t and cos (-t)? they are always equal to each other.cos t = cos (-t) What is the relationship between sin t and sin (-t)? they are always equal to each other.sin t = sin (-t) What is the relationship between sin t and sin (t + 2pi)? they are always equal to each othersin t = sin (t + 2pi) What is the relationship between sin t and sin (t + pi)? they are always opposite to each other What is the relationship between tan t and tan (t + pi)? they are always equal to each othertan t = tan (t + pi) What is the sum of (cos t)^2 + (sin t)^2? (cos t)^2 + (sin t)^2 = 1 What are the radian values for 30, 45, and 60 degrees? 30 degrees = pi/645 degrees = pi/460 degrees = pi/3 AuthorAnonymous ID73804 Card Setezqfdu DescriptionCards for my upcoming trigonometry exam Updated2011-03-19T06:31:54Z Show Answers
