Given the general identity tan x
WebFinal answer. Transcribed image text: Verify the identity. (sinx+ 1)(tanx− secx) = −cosx Expand the product. (sinx+ 1)(tanx− secx) = sinxtanx− sinxsecx+ tanx− Use the Reciprocal Identities, and then simplify. = cosxsin2x − cosxsinx + cosxsinx = Use a Pythagorean Identity, and then simplify. Previous question Next question. WebIt is also true that cos (½π-x) = sin (x) and that cos (x- ½π) = sin (x) So, cos (½π-x) = cos (x- ½π) Sine and cosine are both periodic functions that are identical except for being shifted ½π radians out of phase. Thus, there are a number of ways you can shift them around to be in phase and therefore equal.

WebIn mathematics, an "identity" is an equation which is always true. These can be "trivially" true, like "x = x" or usefully true, such as the Pythagorean Theorem's "a 2 + b 2 = c 2" for … WebSolution. Call t = tan( x 2). Use half angle identities (2) and (3) to transform the equation. 1 − t2 4 + 1 +t2 4 = 1 + t. 1 − t2 +4t = (1 + t)(1 +t2) t3 +2t2 − 3t = t ⋅ (t2 + 2t − 3) = 0. Next, solve the 3 basic trig equations: tan( x 2) = t = 0;tan( x 2) = − 3; and tan( x 2) = 1. Nghi N. · 1 · Apr 12 2015.
