Finding Sin Cos Tan Values [Click Here for Previous Year Questions] Here, to find the sin, cos, tan values, Divide 0,1,2,3, and 4 by 4, then consider their positive roots of them. It can help get the sine ratios, which are, 0, ½, 1/√2, √3/2, and 1 for the angles 0°, 30°, 45°, 60° and 90°. Thus, in the first quadrant, where x and y coordinates are all positive, all six trigonometric functions have positive values. In the second quadrant, only sine and cosecant (the reciprocal of sine) are positive. In the third quadrant, only tangent and cotangent are positive. Finally, in the fourth quadrant, only cosine and secant are positive. The line for the sine of x starts at the origin and passes through the points twenty-four, zero point four, forty, zero point sixty-seven, fifty-two, zero point eight, and ninety, one. It is increasing from the origin to the point ninety, one. The rate of change gets smaller, or shallower, as the degrees, or x-values, get larger. An isosceles triangle with perpendicular side =1 cm and hypotenuse = √2 will give you the value of Sin 45 degrees. (Image Will be uploaded soon) As we know, Sin 45° = Perpendicular/ hypotenuse. Sin 45 ° = AB/AC. Sin 45° = 1 √2. So, the exact value of Sin 45 degree is 1 √2. The exact value of Sin 45 degree in decimal form is 0.7071067812. This question involved the use of the cos-1 button on our calculators. We found cos-1 0.7 and then considered the quadrants where cosine was positive. Remember that the number we get when finding the inverse cosine function, cos-1, is an angle. Now we turn our attention to all the inverse trigonometric functions and their graphs. Properties of Trigonometric Functions. The properties of the 6 trigonometric functions: sin (x), cos (x), tan (x), cot (x), sec (x) and csc (x) are discussed. These include the graph, domain, range, asymptotes (if any), symmetry, x and y intercepts and maximum and minimum points. .
