Answer: sin (45°) = 0.7071067812. sin (45°) is exactly: √2/2. Note: angle unit is set to degrees. Use our sin (x) calculator to find the exact value of sine of 45 degrees - sin (45 °) - or the sine of any angle in degrees and in radians.sin65° = 0.90631. sin 65° = 0.90631. sin 65 degrees = 0.90631. The sin of 65 degrees is 0.90631, the same as sin of 65 degrees in radians. To obtain 65 degrees in radian multiply 65° by π / 180° = 13/36 π. Sin 65degrees = sin (13/36 × π). Our results of sin65° have been rounded to five decimal places. If you want sine 65° with higher ...sin (75 degree) Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals.sin80° = 0.98481. sin 80° = 0.98481. sin 80 degrees = 0.98481. The sin of 80 degrees is 0.98481, the same as sin of 80 degrees in radians. To obtain 80 degrees in radian multiply 80° by π / 180° = 4/9 π. Sin 80degrees = sin (4/9 × π). Our results of sin80° have been rounded to five decimal places.Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.Roman Numerals Radical to Exponent Exponent to Radical To Fraction To Decimal To Mixed Number To Improper Fraction Radians to Degrees ... -\sin^2(x)=\tan^2(x)\sin^2(x ...For sin 36 degrees, the angle 36° lies between 0° and 90° (First Quadrant ). Since sine function is positive in the first quadrant, thus sin 36° value = √ (10 - 2√5)/4 or 0.5877852. . . Since the sine function is a periodic function, we can represent sin 36° as, sin 36 degrees = sin (36° + n × 360°), n ∈ Z. ⇒ sin 36° = sin 396 ...a unit of plane angular measurement that is equal to the angle at the center of a circle subtended by an arc whose length equals the radius or approximately 180°/π ~ 57.3 degrees. secant. the length of the hypotenuse divided by the length of the adjacent side. Also equals 1/cos (θ) sin. sin (θ) is the ratio of the opposite side of angle θ ...Plugging the angle value, in degrees, in the previous formula, we get: α rad = π × 75 /180 = . π × 75÷15/180÷15 = 5π/12 radian, when reduced to lowest fraction in terms of π.. Note: 5π/12 rad can be expressed as real number or as a decimal as 0.41666666666667π rad = 1.3089969389957 radians.In this video, we are going to find the value of the sine of 75 degrees.

2. Multiply the number of degrees by π/180. To understand why you have to do this, you should know that 180 degrees constitute π radians. Therefore, 1 degree is equivalent to (π/180) radians. Since you know this, all you have to do is multiply the number of degrees you're working with by π/180 to convert it to radian terms.Find: sin 75 deg Answer: sin 75 = +- sqrt(2 + sqrt3)/2 Call sin 75 = sin t --> cos 150 = cos 2t On the trig unit circle, cos (150) = cos (180 - 30) = - cos 30 ...First, calculate the sine of α by dividng the opposite side by the hypotenuse. This results in sin(α) = a / c = 52 / 60 = 0.8666. Use the inverse function with this outcome to calculate the angle α = arcsin(0.8666) = 60° (1.05 radians).Online degrees allow busy people to continue their education.
