To solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for the variable. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions.
The function g(x)=-x\sin^2(\frac{1}{x}) has NO fixed point in the interval (0,1] . The continuous extension of g to [0,1] has just one fixed point in [0,1] , i.e. x=0=\lim_{x\to 0}g(x)=0 ...
Free math problem solver answers your trigonometry homework questions with step-by-step explanations.
As many people have pointed out by now, $\sin^2 x$ is simply a "nickname" for $(\sin x)^2$. Therefore, $\sin^2\ 30 = (\sin 30)^2 = (1/2)^2 = 1/4$. As it happens, though, there is another useful thing we can say about $\sin^2 x$:
Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
