WebMar 29, 2014 · 7 years ago. You have to know that sin (30 degrees) = sin (pi/6) is 1/2. This is the only trig function you have to memorize. Then, from the Pythagorean theorem, cos (30) is rt (3)/2. You can figure out sin (45) (see this video). From these you can get all the 12 simplest angles on the unit circle (8 multiples of 30 deg, 4 multiples of 45 (plus ... WebMar 27, 2024 · The exact value of sin(45) is √2 2. Explanation: Consider ABC to be right-angled in B and choose ∠BCA such that its measure is 45o. Since the triangle is isosceles, …

WebFind the value of given trigonometric ratio. Given trigonometric ratio: sin 75 ∘. sin 75 ∘ can be expressed as, sin 75 ∘ = sin ( 45 ∘ + 30 ∘) We know that sin ( A + B) = sin A cos B + cos A sin B. So by applying the above formula we get, sin 75 ∘ = sin 45 ∘ cos 30 ∘ + cos 45 ∘ sin 30 ∘. As, sin 45 ∘ = 1 2, cos 30 ∘ = 3 2 ... WebCalculate sin − 1 ( sin ( 45 ∘)) without a calculator. We know that in this triangle, h 2 = a 2 + a 2. Therefore, h = a 2 + a 2 = 2 a 2 = 2 a. As h can be written as 2 a, we now know how to write an expression for sin ( 45 ∘), sin ( 45 ∘) = a 2 a = 1 2.
