Now, we will calculate the value of cos 90° using the unit circle with the radius 1 unit and the center of the circle placed at the origin of the coordinate axis ‘x’ and ‘y’. Let us take the point P (a,b) anywhere in the circle that forms an angle AOP= x radian. It imp...
Sec 0 degrees is the value of secant trigonometric function for an angle equal to 0 degrees. Understand methods to find the value of sec 0 degrees with examples and FAQs.
±√(sec²(40°) - 1)/sec 40° 1/cosec 40°Note: Since 40° lies in the 1st Quadrant, the final value of sin 40° will be positive.We can use trigonometric identities to represent sin 40° as,sin(180° - 40°) = sin 140° -sin(180° + 40°) = -sin 220° cos(90° -...
