The identities of cosine -148° are as follows:

cos-148°
= sin (90° – 148°) = sin -58°
= sin (90° + 148°) = sin 238°

-cos-148°
= cos (180° – 148°) = cos 32°
= cos (180° + 148°) = cos 328°

Note that cos-148° is periodic: cos (-148° + n × 360°) = cos -148 degrees, n$\hspace{5px} \in \hspace{5px} \mathbb{Z}$.

There are more formulas for the double angle (2 × -148°), half angle ((-148/2)°) as well as the sum, difference and products of two angles such as -148° and β.

What is cos -148°?

In a circle with the radius r, the horizontal axis x, and the vertical axis y, -148 degrees is the angle formed by the two sides x and r; r moving counterclockwise is the positive angle.

As detailed in the unit-circle definition on our homepage, assumed r = 1, in the intersection of the point (x,y) and the circle, x = cos -148°.

Note that you can locate many terms including the cosine-148° value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of cos-148°.

Along the same lines, using the aforementioned form, can you look up terms such as cos -148° value, cos -148, cos-148° value and what is the cos of -148 degrees, just to name a few.

Given the periodic property of cosine of -148°, to determine the cosine of an angle < -360°, e.g. -868°, calculate cos -868° as cos (-868 Mod 360)° = cosine of -148°, or look it up with our form.
