Step 1: Identify the hypotenuse (hyp), adjacent (adj), and opposite (opp) sides of the given right triangle relative to the indicated acute angle. Step 2: Using the following formulas, calculate the trigonometric ratios: $$\begin{align} \sin{\theta} &= \dfrac{\rm{opp}}{\rm{hyp}} ...
How to find {eq}x = tanx? {/eq} Trigonometry Function:The trigonometry function tangent is used on an angle. In a right-angled triangle, the tangent of an angle is {eq}\tan(\theta)=\frac{p}{b} {/eq}, where {eq}p {/eq} is the length of the side opposite to the angle {eq...

Once defined N,A,kr1,theta,fi1,FI,B,kr2 and fi2, run this code: AF=0; forn=1:N; AF=AF+(A(n)*exp(j*kr1*sin(theta)*(cos(fi1(n))*cos(FI)+sin(fi1(n))*sin(FI)))+B(n)*exp(j*kr2*sin(theta)*(cos(fi2(n))*cos(FI)+sin(fi2(n))*sin(FI))); end...
sin(36) = y/4 And therefore y = 4*sin(36) = 2.35 meters. Now we can check whether tan(36) is indeed equal to 2.35/3.24. We find tan(36) = 0.73, and also 2.35/3.24 = 0.73. So indeed we did everything correctly. A right triangle in everyday life ...
