Step 6: Recognize the formula for tan3θWe know that:tan3θ=3tanθ−tan3θ1−3tan2θThus,LHS=tanθ⋅3−tan2θ1−3tan2θ=tan3θThis proves that:tanθ⋅tan(60∘−θ)⋅tan(60∘+θ)=tan3θ Step 7: Find the
2.: Using the formula, we can rewrite the equation: Therefore, we can equate: 3tan(3θ)=3 3.Simplify the Equation: Dividing both sides by 3 gives: tan(3θ)=1 4.Find the General Solution: The general solution fortan(3θ)=1is: ...
In order to prove any trigonometric identity equations, we must know the various trigonometric identity formulae. The proof needs just the manipulations and rearrangement in various forms. The following identities will be sufficient to prove this one: 1+cos2θ=2cos2θ1−cos2θ=2...
If theta = -7pi/4, find tan(theta). If theta = 8pi/3, find tan(theta). If VxW=(2,-3,5) and V*W=3, find tan(theta) where theta is the angle between V and W. If tan(\theta) = -\dfrac{3}{7}; \; 270^{\circ} \theta 360^{\circ}, then find the va...
We can understand this formula by looking at a right triangle with an angle theta and the opposite side x and adjacent side 1. By using the Pythagorean theorem, we can solve for the hypotenuse as √(1+x2). Then, we can use the definition of the inverse sine function to find the ...
