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 The tangent of x is defined to be its sine divided by its cosine tanx = sinx cosxFree math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with stepbystep explanations, just like a math tutor Tan^2xtan^2y=sec^2xsec^2y and, how do you factor and simplify, cscx(sin^2xcos^2xtanx)/sinxcosx PreCalc 1) Use an Addition or Subtraction Formula to write the expression as a trigonometric function of one number cos 12° cos 18° − sin 12° sin
