Trigonometry is a branch of There are an enormous number of uses of trigonometry and its formulae. For example, the technique of triangulation is used in Geography to measure the distance between landmarks; in Astronomy, to measure the distance to nearby stars and also in satellite navigation systems. View Result Trigonometry Formulas List When we learn about trigonometric formulas, we consider them for right-angled triangles only . In a right-angled triangle, we have 3 sides namely – Hypotenuse, Opposite side (Perpendicular), and Adjacent side (Base). The longest side is known as the hypotenuse, the side opposite to the angle is perpendicular and the side where both hypotenuse and opposite side rests is the adjacent side. Here is the list of formulas for trigonometry. • • • • • • • • • • • • Basic Trigonometric Function Formulas There are basically 6 ratios used for finding the elements in Trigonometry. They are called trigonometric functions. The six trigonometric functions are sine, cosine, secant, cosecant, tan...

Adjacent is always next to the angle And Opposite is opposite the angle Sine, Cosine and Tangent Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same no matter how big or small the triangle is To calculate them: Divide the length of one side by another side Example: What is the sine of 35°? Usingthistriangle(lengthsare only to one decimal place): sin(35°) = Opposite Hypotenuse = 2.8 4.9 = 0.57... cos(35°) = Adjacent Hypotenuse = 4.0 4.9 = 0.82... tan(35°) = Opposite Adjacent = 2.8 4.0 = 0.70... Size Does Not Matter The triangle can be large or small and the ratio of sides stays the same. Only the angle changes the ratio. Try dragging point "A" to change the angle and point "B" to change the size:

Now to remember the Trigonometric table for 120 to 360 , we just to need to remember sign of the functions in the four quadrant. We can use below phrase to remember ALL SILVER TEA CUPS ALL – All the trigonometric function are positive in Ist Quadrant SILVER – sin and cosec function are positive ,rest are negative in II Quadrant T EA – tan and cot function are positive, rest are negative in III Quadrant CUPS – cos and sec function are positive , rest are negative in IV quadrant Now we can use the formula in below table to calculate the ratios from 120 to 360 This table is very easy to remember, as each correspond to same function.The sign is decided by the corresponding sign of the trigonometric function of the angle in the quadrant For example a. $ \cos 120 = \cos (180 -60) = – \cos 60$ . It is easy to remember and sign is decided by the angle quadrant. Since 120 lies in II quadrant ,cos is negative b.$\sin 120 = \cos (180 -60) = \sin 60$. Here since sin is positive in II quadrant, we put positive sign c. $\tan 120 = \tan (180 -60) = – \tan 60$. Here since tan is negative in II quadrant, we put negative sign Now Trigonometric table for 120 to 180 is given by And it is calculated as $\sin (120) = \sin (180 -60) =\sin 60= \frac $ We have explained everything is terms of degrees, same thing can be done in radian form also Related Posts September 25, 2020 at 9:51 pm add (all trigonometric function are positive in 1st quadrant) sugar(sin is positive and all 3 remaining function...
