WebNotice also that sin θ = cos (π 2 − θ), sin θ = cos (π 2 − θ), which is opposite over hypotenuse. Thus, when two angles are complementary, we can say that the sine of θ θ equals the cofunction of the complement of θ. θ. Similarly, tangent and cotangent are cofunctions, and secant and cosecant are cofunctions. WebUnit 1: Right triangles & trigonometry. 0/700 Mastery points.

Then using the definitions of the trig functions [sin = opposite/hypotenuse; cos = adjacent/hypotenuse; tan = opposite/adjacent; etc] we find: tanΘ = 12/5. cscΘ = 13/12 (csc is the inverse of sin) Webcos( ) = 1 cos( ) = sec( ) An odd function is a function f(x) with the property that f( x) = f(x). Examples include x3, x5, x7, sine, and tangent. Cosecant and cotangent are odd functions, meaning that csc( ) = csc( ) and cot( ) = cot( ). We can check that these identities are true by using that sine is an odd function and that cosine is even ... t-test apa table
