Web11 Feb 2024 · sec(t) = a + 1 4a. Since tan2(t) + 1 = sin2(t) cos2(t) + 1 = sin2(t) + cos2(t) cos2(t) = 1 cos2(t) = sec2(t) so tan2(t) = sec2(t) − 1 = (a + 1 4a)2 − 1 = a2 + 1 2 + 1 16a2 − 1 = a2 − 1 2 + 1 16a2 = (a − 1 4a)2 so tan(t) = ± (a − 1 4a) Therefore tan(t) + sec(t) = a + 1 4a ± (a − 1 4a) = 2a or 1 2a. Share Cite Follow answered Feb 11, 2024 at 4:39 The following (particularly the first of the three below) are called "Pythagorean" identities. sin 2 ( t) + cos 2 ( t) = 1. tan 2 ( t) + 1 = sec 2 ( t) 1 + cot 2 ( t) = csc 2 ( t) Advertisement. Note that the three identities above all involve squaring and the number 1. See more Notice how a "co-(something)" trig ratio is always the reciprocal of some "non-co" ratio. You can use this fact to help you keep straight that … See more By the way, in the above identities, the angles are denoted by Greek letters. The a-type letter, "α", is called "alpha", which is pronounced "AL-fuh". The b-type letter, "β", is called "beta", which is pronounced "BAY-tuh". See more You will be using all of these identities, or nearly so, for proving other trig identities and for solving trig equations. However, if you're going on to study calculus, pay particular attention to … See more The above identities can be re-stated by squaring each side and doubling all of the angle measures.

WebParametric Equations - Basic Shapes. A circle centered at (h,k) (h,k) with radius r r can be described by the parametric equation. x=h+r\cos t, \quad y=k+r\sin t. x = h+rcost, y = k +rsint. Eliminating t t as above leads to the familiar formula. (x-h)^2+ (y-k)^2=r^2. (x−h)2 +(y −k)2 = r2. What are the radius r r and center (h,k) (h,k) of.
