The value of sin, cos, and tan of some angles are equal to the values of sin, cos, and tan of other angles. Let us take an example of cos(-30⁰). Since 30 degrees lie in the first quadrant we can say that cos(-30⁰) is equal to cos(30⁰) because all the angles in t...
Value of cos 180 degrees can be obtained with the help of unit circle and trigonometric sin and cos functions from other angles like 0, 90, and 270 degrees. Learn cosine pi (π) value with derivation at BYJU'S.
Now, we square the value ofcos60∘: cos260∘=(12)2=14 Step 3: Findsin30∘ Next, we know that: sin30∘=12 Step 4: Calculatesin230∘ Now, we square the value ofsin30∘: sin230∘=(12)2=14 Step 5: Addcos260∘andsin230∘ ...
-cos(90° + 8°) = -cos 98° Sin 8 Degrees Using Unit Circle To find the value of sin 8 degrees using the unit circle: Rotate ‘r’ anticlockwise to form a 8° angle with the positive x-axis. The sin of 8 degrees equals the y-coordinate(0.1392) of the point of intersection (...
