Inverse sine,cos, tan --What they are and how to use them to find the measure of an angle in a right triangle.
How do you use a calculator to find x if sin(x) = 3/5? Find the following trigonometric function without using a calculator: cos (30^o). If you use the inverse sine to find the measure of an angle with a given sine, explain how you can calculate the measure of another (non-co...

In fact, in any given right triangle, a function known as “sine,” abbreviated sin, relates the ratio between the opposite side of an angle and the hypotenuse. Using this knowledge of the ratio of the opposite side and the hypotenuse, you can calculate the specific angle in the triangle ...
Let’s understand how to calculate the value of sin 18 degrees here. How to Find Sin 18 Degree Value Let θ = 18°….(i) We can write 90° as: 90° = 36° + 54° 90 = 2 × 18° + 3 × 18° Substituting (i) in the above equation, ...
Are you trying to compute the inverse Fourier Transform of the Heaviside function and compare it with Heaviside function?
How does someone calculate the percentage of something? How do I do decimal long division? Give the domain of the square root of (x - 3). When dividing polynomials, how do you know if you are going to add your remainder or subtract your remainder? (2y)2 + 3y +-2y+5 / 3y-1 Can...
sin(x) = opposite/hypothenuse cos(x) = adjacent/hypothenuse tan(x) = opposite/adjacent A right triangle Pixabay Calculating an Angle in a Right Triangle The rules above allow us to do calculations with the angles, but to calculate them directly we need the inverse function. An inverse fu...
ca sin b these formulas are very easy to remember and also to calculate. for example, if, in ∆abc, a = 30° and b = 2, c = 4 in units. then the area will be; area (∆abc) = ½ bc sin a = ½ (2) (4) sin 30 = 4 x ½ (since sin 30 = ½) =...
