sin squared plus cosine squared equals to a constant. 因此,证明了sin方+cos方始终为常数。 经过这些解释和推理,我们已经更好地理解了sin方+cos方的几何意义以及它为常数的证明。接下来,我们将进一步分析和讨论sin方+cos方在不同角度取值变化特点,以及它与其他函数的关系以及在实际应用中的作用和意义。 3. 分...
The Pythagorean identity is the identity that originated from the Pythagorean theorem. 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 ...
In trigonometry, Pythagorean identity states that the sum of sine-squared and cosine-squared of the same angle is always equal to 1: sin2(x)+cos2(x)=1. This property would be helpful in verifying whether the given equation is true or false.Answer and Explanati...
If x + y = 12 and xy equals 50, what does x squared plus y squared equal to? What is \ln(2x)-\ln(2) equivalent to? What is arctan(x) equal to? Let f(x) = 1/x+12. What is f-1(x)? (a^(-2) + 4)^9 equals A) a^(-18) + 36a^(-16) + 1,152a^(-14) + ...
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...
