IMHO you are not the only one and not totally at fault to be confused - sin 2 x as far as I can see is a sort of mathematical slang, not strictly logical (so no wonder your calculator doesn't understand it either) which by its antiquity is let through and is universal - so there it is to get used to. Solve for ? sin(x/2)=1/2. Take the inverse sine of both sides of the equation to extract from inside the sine. The exact value of is .
tan 2 (x) + 1 = sec 2 (x). cot 2 (x) + 1 = csc 2 (x). sin(x y) = sin x cos y cos x sin y. cos(x y) = cos x cosy sin x sin y sin 2 x MEANS (sin x) 2. Which you can calculate on your calculator.

Sin^2 x is “sine-squared of x” which is a different function from the sine function. Free Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step The fixed point iteration x n+1 = sin(x n) with initial value x 0 = 2 converges to 0. Zero is the only real fixed point of the sine function; in other words the only intersection of the sine function and the identity function is sin(0) = 0.

2020-02-13 · Misc 10 Find sin 𝑥/2, cos 𝑥/2 and tan 𝑥/2 for sin𝑥 = 1/4 , 𝑥 in quadrant II Given that x is in quadrant II So, 90° < x < 180° Replacing x with 𝑥/2 (90°)/2 < 𝑥/2 < (180°)/2 45° < 𝑥/2 < 90° So, 𝑥/2 lies in Ist quadrant In Ist quadrant, sin , cos & tan are positive sin 𝑥/2 ,
Is there any solution for the equation sin x = 2? The answer is yes if you accept complex numbers. However, the reader should know a bit of complex numbers and trigonometry.
