Exact value of csc 30
Did you know?
WebFor sec 30 degrees, the angle 30° lies between 0° and 90° (First Quadrant ). Since secant function is positive in the first quadrant, thus sec 30° value = 2/√3 or 1.1547005. . . Since the secant function is a periodic function, we can represent sec 30° as, sec 30 degrees = sec (30° + n × 360°), n ∈ Z. ⇒ sec 30° = sec 390° = sec ... WebLet us list out the values of trigonometric functions at known angles. (i) The values given above are all exact. (ii) We observe that sin 30 ° and cos 60 ° are equal. Also sin 60 ° and cos 30 ° are equal. (iii) The value of reciprocal ratios namely cosecant, secant and cotangent can be obtained using the above table.
WebJun 26, 2024 · From this information, we know. tanx = 1 2 2sinx = √2 2 2 2cosx = √2 2. We can plug these values into our expressions for the reciprocal identities to get. cotx = 1 1 = 12 2 cscx = 1 √2 2 = √2 2 2secx = 1 √2 2 = √2. Remember for csc45∘ and sec45∘, we had to rationalize the denominator.

Because we're dividing by 0, it is undefined. If we tried to make a right triangle on the unit circle with points at the origin, or (0,0), and the point (1,0) with an angle of 180°, our third point would be ( −1,0).
