what is 1 cos The Trigonometric Identities are equations that are true for Right Angled Triangles Periodicity of trig functions Sine cosine secant and cosecant have period 2 while tangent and cotangent have period Identities for negative angles Sine tangent cotangent and cosecant are odd functions while cosine and secant are even functions
1 cosx secx How do you apply the fundamental identities to values of theta and show that they are true If n 1 is a positive integer then cosnx cosx n This is a convenience of notation to avoid having to use parentheses to distinguish for example cosx 2 and cos x2 By convention we can write cos2x and cosx2 respectively without ambiguity However in the case of 1 we have a clash of notation If f x is a function then f 1
