Community Tip - You can change your system assigned username to something more personal in your community settings. I had one bad mark on my math exam at school. The question was - what is the sine of 45 degrees. I immediately drew a rectangular triangle with single legs in my head and gave the answer - one divided by the root of two: the leg divided by the hypotenuse. But I heard from the teacher that the answer is wrong. The correct answer is the root of two divided by two: this is how it is written in all textbooks! And, actually, why? Go to Solution. Its kind of a math convention and there are some reasons for doing so, though. On one hand its easier to quickly estimate the value of a numerical fraction if the denominator is rational, preferably a natural number. It can make subsequent calculations easier. And sometimes it makes even more sense to rationalize the nominator instead of the denominator - just think of some kind of limits like. So, is it wrong not to rationalize the denominator?

Ans: Let us find the exact value of Sin 45 using an isosceles triangle.

Use this sin calculator to easily calculate the sine of an angle given in degrees or radians. Calculating Sin x is useful in right triangles such as those formed by the heights in different geometric shapes. The sine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the opposite side to the longest side of the triangle. Since for a right triangle the longest side is the hypotenuse and it is opposite to the right angle, the sine of a right angle is equal to the ratio of the hypotenuse to itself, thus equal to 1. You can use this sine calculator to verify this. A commonly used law in trigonometry which is trivially derived from the sine definition is the law of sines :. The sine function can be extended to any real value based on the length of a certain line segment in a unit circle circle of radius one, centered at the origin 0,0 of a Cartesian coordinate system.

Using trigonometry formulas, we can represent the sin 45 degrees as:. In a right-angled triangle, the Sine function can be defined as the ratio of the length of the opposite side of a triangle to its hypotenuse. Is sin 45 degrees the same as cos 45 degrees? Sin Here are some key aspects of their importance:. A mnemonic to remember the value of sin 45 degrees is Square root of 2 over 2, or simply remember the approximate value 0. Adjacent side divided by the hypotenuse. In the general population of non-mathematicians and non-scientists, trigonometry is mainly thought to be useful in measurement problems. The table consists of a list of angles in radians, and the corresponding value of the sine function for each angle. Babylonians, the Egyptians based trigonometry on their base 60 numeral system. It is necessary to talk about the importance of Sine functions in trigonometry before having a discussion on Sin 45 degrees.
