2016年3月3日 · Cosin của hai góc đối bằng nhau; sin của hai góc bù nhau thì bằng nhau; phụ chéo là 2 góc phụ nhau thì sin góc này = cos góc kia, tan góc này = cot góc kia; tan của hai góc hơn kém pi thì bằng nhau.

A basic trigonometric equation has the form sin(x)=a, cos(x)=a, tan(x)=a, cot(x)=a

Trigonometry mainly provides six functions for sine (sin), cosine (cos), and tangent (tan), also its reciprocal functions cosecant (csc), secant (sec), and cotangent (cot). These processes help in solving angle and distance related problems in both 2D and 3D surroundings.

The fixed point iteration x n+1 = cos(x n) with initial value x 0 = −1 converges to the Dottie number. 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 {\displaystyle \sin(0)=0} .

A formula for computing the trigonometric identities for the one-third angle exists, but it requires finding the zeroes of the cubic equation 4x 3 − 3x + d = 0, where is the value of the cosine function at the one-third angle and d is the known value of the cosine function at the full angle.

sin-1 (–x) = – sin-1 x; cos-1 (–x) = π – cos-1 x; tan-1 (–x) = – tan-1 x; cosec-1 (–x) = – cosec-1 x; sec-1 (–x) = π – sec-1 x; cot-1 (–x) = π – cot-1 x; What is Sin 3x Formula? Sin 3x is the sine of three times of an angle in a right-angled triangle, which is expressed as: Sin 3x = 3sin x – 4sin 3 x

sin 2 θ means to find the sine of θ, then square the result, but; sin θ 2 means to square θ, then do the sine function
