Derivatives of Trigonometric Functions
www.ocf.berkeley.eduand use them to find the derivatives of other trigonometric functions. d dx sin(x) = cos(x) and d dx cos(x) = −sin(x) To remember which derivative contains the negative sign, recall the graphs of the sine and cosine functions. At x = 0, sin(x) is increasing, and cos(x) is positive, so it makes sense that the derivative is a positive cos(x).
Tangent, Cotangent, Secant, and Cosecant
math.dartmouth.edufunctions later in the course. The Other Trigonometric Functions So far in this course, the only trigonometric functions which we have studied are sine and cosine. Today we discuss the four other trigonometric functions: tangent, cotangent, secant, and cosecant. Each of these functions are derived in some way from sine and cosine.
11.3 FOURIER COSINE AND SINE SERIES
www.personal.psu.eduSee Figures 11.3.1 and 11.3.2. The trigonometric cosine and sine functions are even and odd functions, respectively, since cos(x) cos x and sin(x) sin x. The exponential functions f(x) ex and f(x) e x are neither odd nor even. PROPERTIES The following theorem lists some properties of even and odd functions. f(x) 2x is even since f(x) (x)2 x2 f ...
Introduction to trigonometric functions - University of Sydney

These trigonometric functions are extremely important in science, engineering and mathematics, and some familiarity with them will be assumed in most first year university mathematics courses.
