Math - Solving Trig Equations
Start by recalling the most important identity. My math teacher calls this "the #1 Identity." sin^2(x) + cos^2(x) = 1 We want to simplify our trig equation by writing everything in terms of sine. Let's solve the #1 Identity for cos^2(x) because we have that in ...

could someone please refresh my memory of the basic trig functions? ex) cos^2 + sin^2 = 1? That is a trig identity. http://www.sosmath.com/trig/Trig5/trig5/trig5.html

they are all correct but I would write tanß = 4/5 also you have no angle after your trig names to say sin = 4/5 is a sin. (math joke)

Trig 30
x/2 = 2pi/3 yields a unique solution of x = 4pi/3 Does this answer come from some trig equation? Your subject title suggests that. In that case find the period of the trig function, then add k(period) to 4pi/3, k an integer.

Subtract 2 pi from 7pi/3. The trig functions of 7 pi/3 will be the same values as the trig functions of pi/3, which is 60 degrees. The cosine of pi/3 is 1/2. That makes the secant 3. The tangent is sqrt3 You should be able to look up or figure out the other funtions of that ...
