(sin \phi)^2 is equal to sin^2\phi. sin^260 + cos^260 + tan^245 + sec^260 - cosec^260 The trick to that is to use a few trigonometric identities. \sin^2\theta + \cos^2\theta = 1 \tan 45 = 1 ...

Trigonometry mainly provides six functions for sine (sin), cosine (cos), and tangent (tan), also its reciprocal functions cosecant (csc), secant (sec), and cotangent (cot). These processes help in solving angle and distance related problems in both 2D and 3D surroundings.

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. The exact value of sin(60) sin (60) is √3 2 3 2. The result can be shown in multiple forms. 0.86602540… 0.86602540 …

To evaluate this expression, we need to find the values of the trigonometric functions and then simplify. 1. sin (60°) = √3/2 2. tan (30°) = 1/√3 3. sec (45°) = √2 Now, substitute these values into the expression: (2 (√3/2)² - (1/√3)²) / (√2)² Simplify: (2 (3/4) - 1/3) / 2 = (3/2 - 1/3) / 2 = (9/6 - 2/6) / 2 = (7/6) / 2 = 7/12
