It states the addition of the sine squared function and cosine squared function results in a numerical value one. The identity is as follows: $$\sin^2 \theta + \cos^2 \theta = 1 $$ Answer and Explanation: Given trigonometric expression...
The fundamental trigonometric identity establishes that the squared sum of the sine and cosine of an angle equals 1, {eq}\sin^2 x+\cos^2 x=1 {/eq}. This identity allows us to express the cosine as a function of the sine and vice versa. In fact, by knowing the va...

For the first time, a hard wear-resistant multi-layer of TiCrN-TiAlN-TiAlSiN-TiAlSiCN was deposited on carbon steel CK45-based tillage tools to increase their useful lifetime. The layers were deposited by using an arc-PVD method without post-annealing pr
