Google can even work with trigonometric functions, including sine and cosine. Google. 甚至能用三角函數(shù)計(jì)算，包括正弦和余弦。
A new stimulation technique named combined sine-wave method was designed based on the theory of orthogonality of trigonometric function. 針對(duì)實(shí)驗(yàn)環(huán)境下橋梁節(jié)段模型的氣動(dòng)導(dǎo)數(shù)辨識(shí)，提出了組合正弦激勵(lì)方法。
Sine and Cosine is the triangular relationship between the corners and trigonometric functions of the most common, the two most important theorems. 正、余弦定理的幾點(diǎn)應(yīng)用 摘 要 正弦定理和余弦定理是三角形邊角關(guān)系及三角函數(shù)種最常見、最主要的兩個(gè)定理。
