We should learn it like cos 0 sin 90 1 cos 30 sin 60 32 cos 45 sin 45 12 cos 60 sin 30 12 cos 90 sin 0 0 So for cos it will be like 1 32 12 12 0 For tan.

Before discussing Sin 45 degrees let us know the importance of Sine function in trigonometry. For memorising cos 0 cos 30 cos 45 cos 60 and cos 90 Cos is the opposite of sin. Advertisement Remove all ads.

The answer is as follows. As the third side of the triangle does not exist length is 0 the cosine equals zero 0 divided by the length of the hypotenuse equals 0. The value of cos function when angle of right triangle equals to 45 is called cosine of angle 45 degrees.

I have noticed that students cannot actually remember values of six trigonometric ratios sin cos tan cosec sec and cot for 0 30 45 60 and 90These values are used very often and it is recommended from my point of view that student should be able to tell the values instantly when asked. What is cos 45 degrees. It is expressed as cos 45 in mathematics as per sexagesimal system.

Exact values of sin45 cos45 tan45 csc45 sec45 cot45 Find exact values of all trigonometric functions when the angle is 45 degreesblackpenr. For example to get the COS of 60 degrees you can use either formula below. The Trignometric Table of sin cos tan cosec sec cot is useful to learn the common angles of trigonometrical ratios from 0 to 360.

The cosine of a 90-degree angle is equal to zero since in order to calculate it we would need a triangle with two 90-degree angles which is the definition of a straight line. 2 2 2 2 The result can be shown in multiple forms. Sin 45 Degrees In trigonometry there are three primary ratios Sine Cosine and Tangent which are used to find the angles and length of the right-angled triangle.

Cos 45 cos 45 The exact value of cos45 cos 45 is 2 2 2 2. This is an isosceles triangle so the base angles are 45 the hypotenus is 2 from Pythagoras theorem and so the c o s 45 is adjacent over hypotenuse which is 1 2 EDITED to correct for some Latex errors 123K views.
