what is sec 90 degrees 90 degrees is a right angle Sec x 1 cos x Sec 90 1 cos 90 Sec 90 1 0 Sec 90 undefined Sec 90 minus Theta Let s derive the formula for sec 90 degrees minus theta Sec 90 Theta sec 90 sec 1 90 Here 90 is multiplied by 1 an odd number so sec will change to cosec
Step 1 Create a table with the top row listing the angles such as 0 30 45 60 90 and write all trigonometric functions in the first column such as sin cos tan cosec sec cot Step 2 Determine the value of sin To determine the values of sin divide 0 1 2 3 4 by 4 under the root respectively See the example below In a right triangle the two variable angles are always less than 90 See Interior angles of a triangle But we can in fact find the secant of any angle no matter how large and also the secant of negative angles For

Sec 90 sec 90 Rewrite sec 90 sec 90 in terms of sines and cosines 1 cos 90 1 cos 90 Apply the reference angle by finding the angle with equivalent trig values in the first quadrant Make the expression negative because cosine is negative in the third quadrant 1 cos 90 1 cos 90 The cosine of the angle equal to 900 is equal to 0 So secant of the angle equal to 90o can be written as 1 0 The quotient of when the divisor is zero is undefined and hence it is considered as There is a detailed description of how to calculate Sec 90 value in the subsequent sections
