This trigonometry calculator will help you in two popular cases when trigonometry is needed. If you want to find the values of and their reciprocal functions, use the first part of the calculator. Searching for the missing, using trigonometry? Our tool is also a safe bet! Type 2-3 given values in the second part of the calculator and in a blink of an eye you'll find the answer.

Math.cos (x) ¶ Return the cosine of x radians. Math.hypot (x, y) ¶ Return the Euclidean norm, sqrt(x.x + y.y). This is the length of the vector from the origin to point (x, y). Math.sin (x) ¶ Return the sine of x radians. Math.tan (x) ¶ Return the tangent of x radians.

Scroll down if you want to read more about what is trigonometry and where you can apply it.There are many other tools useful when dealing with trigonometry problems. Check out two popular trigonometric laws: and calculators, helping to solve any kind of a triangle.

If you want to read more about the trigonometric functions, go to our dedicated tools:. What is trigonometry?Trigonometry is a branch of mathematics. The word itself comes from the Greek trigōnon (which means 'triangle') and metron ('measure'). As the name suggests, trigonometry deals mostly with angles and triangles; in particular, it's defining and using the relationships and between angles and sides in triangles. The primary application is thus solving triangles, specifically right triangles, but also any other type of triangle you like.Trigonometry has plenty of applications: from everyday life problems such as calculating the height or distance between objects to the satellite navigation system, astronomy, and geography.

Also, sine and cosine functions are fundamental for describing periodic phenomena - thanks to them, we can describe oscillatory movements (as ) and waves like sound, vibration or light.Many different fields of science and engineering use trigonometry and trigonometric functions, to mention only a few of them: music, acoustics, electronics, medicine and medical imaging, biology, chemistry, meteorology, electrical, mechanical and civil engineering, even economics. The trigonometric functions are really all around us! Trigonometry calculator as a tool for solving right triangleTo find the missing sides or angles of the right triangle, all you need to do is enter the known variables into the trigonometry calculator.

You need only two given values in the case of:. one side and one angle. two sides. area and one sideRemember that if you know two angles, it's not enough to find the sides of the triangle.

Sin Cos Tan Examples

Two triangles having the same shape (which means they have equal angles) may be of different sizes (not the same side length) - that kind of relationship is called triangle similarity. If the sides have the same length, then the triangles are congruent.

Sin Cos Tan

In any right angled triangle, for any angle:The sine of the angle = the length of the opposite sidethe length of the hypotenuseThe cosine of the angle = the length of the adjacent sidethe length of the hypotenuseThe tangent of the angle = the length of the opposite sidethe length of the adjacent sideThe hypotenuse of a right angled triangle is the longest side, which is the one opposite the right angle. The adjacent side is the side which is between the angle in question and the right angle. The opposite side is opposite the angle in question.sin = o/h cos = a/h tan = o/aOften remembered by: soh cah toaExample:Find the length of side x in the diagram below.
