Trigonometric Functions of Acute Angles For real number x, the notations sin x, cos x, etc. refer to the value of the trigonometric functions evaluated at an angle of x rad. If units of degrees are intended, the degree sign must be explicitly shown (e.g., sin x°, cos x°, etc.). Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history Solve your math problems using our free math solver with step-by-step solutions.

(The notation sin 2 (x) is equivalent to (sin(x)) 2.Warning: sin-1 (x) stands for arcsin(x) not the multiplicative inverse of sin(x).). By observing the graphs of sine and cosine, we can express the sine function in terms of cosine and vice versa: Click here👆to get an answer to your question ️ If xsin^3 theta + ycos^3 theta = sinthetacostheta and xsintheta = ycostheta , prove that x^2 + y^2 = 1 .
