WitrynaInverse Secant sec-1 Sec-1 arcsec Arcsec. The inverse function of secant.. Basic idea: To find sec-1 2, we ask "what angle has secant equal to 2?" The answer is 60°. As a result we say that sec-1 2 = 60°. In radians this is sec-1 2 = π/3.. More: There are actually many angles that have secant equal to 2. Witrynathe solutions tell us to divide both sides by cos^2. so sin^2/cos^2 + cos^2/cos^2 = 1/cos^2 and 1/cos^2 is sec^2 << still following then somehow it says therefore tan^2-1 = sec^2 so it replaces the entire first argument with sec^2, completely ignoring that 1 we were supposed to deduct from tan.

"Witryna12 sie 2016 · Explanation: Let the answer be x. Since sec−1(2) = x, sec(x) = 2. As secant is the reciprocal of the cosine function, i.e. sec(x) = 1 cos(x), the following must be true as well. 1 cos(x) = 2. Or cos(x) = 1 2. The range of sec−1(x) is [0, π 2) ∪ ( π 2,π]. The range of cos−1(x) is [0,π]. Since the ranges are similar, we can find x using. " - Is sec 2 the same as 1/cos 2

WitrynaFor the next trigonometric identities we start with Pythagoras' Theorem: The Pythagorean Theorem says that, in a right triangle, the square of a plus the square of b is equal to the square of c: a 2 + b 2 = c 2. Dividing through by c2 gives. a2 c2 + b2 c2 = c2 c2. This can be simplified to: ( a c )2 + ( b c )2 = 1. WitrynaDifference between cos^-1 and secant - cos^-1 is the inverse of cos (1/cos) and - secant is also 1/cos But my math teacher says they're different. What am I missing?

WitrynaNow, using the trigonometric identity: 1+tan 2 a = sec 2 a. sec 2 A = 1 + (3/4) 2. sec 2 A = 25/16. sec A = ±5/4. Since, the ratio of lengths is positive, we can neglect sec A = 5/4. Therefore, sec A = 5/4. Example 2: (1 – sin A)/(1 + sin A) = (sec A – tan A) 2. Solution: Let us take the Left hand side of the equation. L.H.S = (1 – sin A ...
