Example 1:To find the domain of a function f(x) = √(x + 3), we apply the rule 2 mentioned above. Then we get: x + 2 ≥ 0. Solving thisinequality, we get x ≥ -2. Thus, the domain of f(x) is [-2, ∞). Example 2:To calculate the domain of a function g(x) = (2...
The domain for the inverse sine function is −1≤x≤1 because this is the range for the sine function. The range for the function is the same as the range for thecosine function, −1≤f(x)≤1 Use the identity cos(x)=±1−sin2(x) f(x)=±1−sin2...
sin2x ≤ 1 sin x ∈ [-1, 1] Hence, we got the range and domain for sine function. Similarly, following the same methodology, 1- cos2x ≥ 0 cos2x ≤1 cos x ∈ [-1,1] Hence, for the trigonometric functions f(x)= sin x and f(x)= cos x, the domain will consist of the ...
Why isn't the domain and range of {eq}\mathrm{arcsin}(x) {/eq} the same?Question:Why isn't the domain and range of {eq}\mathrm{arcsin}(x) {/eq} the same?Domain and rangeThe domain of the function are the set of values that we can be directly give as an input to a function...
The sine function is not one-to-one, but once we restrict its domain to -π/2 to π/2, the restricted sine function IS one to one. The inverse sine function, denoted arcsin or sin-1, is the inverse of this restricted sine function....

MDS, which is the pressure needed to reduce Xmax to one-half of its initial value, plotted as a function of titanium concentration. Also plotted is the inverse of the magnetostriction constant (λs) determined by Syono (1965) at 290 and 220 K. An additional problem to address pertains to...

When the IPMSM operates in the high-speed domain, a sliding mode observer (SMO) extended Kalman filter based on the inverse EMF method can be used to obtain the rotor angle of the motor. The sensorless motor runs stably throughout the process, and the above two observer algorithms can be ...
Where did this graph come from?We learn about sin and cos graphs later inGraphs of sinxand cosx Note 1:Because we are assuming that only real numbers are to be used for thex-values, numbers that lead todivision by zeroor toimaginary numbers(which arise from finding the square root of ...
