The value of the tan function for any angle θ in terms of sin and cos can be given using the formula, tan θ = sin θ/cos θ. How to Find Value of Tan Using Sin and Cos? Using the sin cos tan table, we can directly find the sin cos tan values for these angles and use in problems. The trigonometry table or chart for sin, cos, and tan are used to find these trigonometric values for standard angles 0 o, 30 o, 45 o, 60 o, and 90 o. What is the Table for Sine, Cosine, and Tangent in Trigonometry? To find sin, cos, and tan we use the following formulas:įor finding sin, cos, and tan of standard angles, you can use the trigonometry table. To solve any problem, we first draw the figure that describes the problem and we use the respective trigonometric ratio to solve the problem. We can use sin cos and tan to solve real-world problems. Sin, cos, and tan are the basic trigonometric ratios in trigonometry, used to study the relationship between the angles and sides of a triangle (especially of a right-angled triangle). Therefore, the ladder reaches up to 11.9 ft of the wall.įAQs on Sin Cos Tan What is Meant By Sin Cos Tan in Trigonometry? Here, tan 50 o is calculated using the calculator and the final answer is rounded up to 1 decimal. So we use the relation between the opposite and the adjacent sides which is tan. Here, we know the adjacent side (which is 10 ft) and we have to find the opposite side (which is x ft). Let us assume that the ladder reaches till x ft of the wall. If the ladder is at a distance of 10 ft from the wall, then up to what height of the wall the ladder reaches? Here is an example to understand the applications of sin, cos and tan.Įxample: A ladder leans against a brick wall making an angle of 50 o with the horizontal. We use sin, cos, and tan to solve many real-life problems. Trigonometry ratios sin, cos, tan find application in finding heights and distances in our daily lives. We can use the acronym "SOHCAHTOA" as shown below, Trick to remember sin cos tan formulas in trigonometry: Here is a trick to remember the formulas of sin, cos, and tan. Now we find sin θ, cos θ, and tan θ using the above formulas: The side adjacent to θ is the adjacent side or base. The side opposite to θ is the opposite side or perpendicular. In the triangle, the longest side (or) the side opposite to the right angle is the hypotenuse. Let us understand these sin, cos, and tan formulas using the example given below.Įxample: Find the sin, cos, and tan of the triangle for the given angle θ. Here are the formulas of sin, cos, and tan.Īpart from these three trigonometric ratios, we have another three ratios called csc, sec, and cot which are the reciprocals of sin, cos, and tan respectively. Sin, cos, and tan functions in trigonometry are defined in terms of two of the three sides (opposite, adjacent, and hypotenuse) of a right-angled triangle. Let us understand the formulas to find these ratios in detail in the following sections. We can find the sin, cos and tan values for a given right triangle by finding the required ratio of the sides. Sin, Cos, and Tan values in trigonometry refer to the values of the respective trigonometric function for the given angle. The "adjacent side" or the base is the side(other than the hypotenuse) that "touches" the angle.
