A cosine wave is the mirror image of a sine wave. Enter the angle and the calculator will instantly calculate its acute reference angle in either degrees or radians. For example, if one needs to find cot() and it is known that the adjacent side b = 6 and c = 20, then cos() = 6 / 20 = 0.3. Steps to calories calculator helps you to estimate the total amount to calories burned while walking. Additional data concerning your triangle: missing sides or angles, side length ratio, area, perimeter gets calculated as well. As we remember from basic triangle area formula, we can calculate the area by multiplying the triangle height and base and dividing the result by two. There arise two cases which are as follows: Below are the formulas to find reference angle in degrees: First Quadrant: \(0^\text{o} 90^\text{o}\), Second Quadrant: \(90^\text{o} 180^\text{o}\), $$ \text{Reference Angle} = 180^\text{o} Angle $$, Third Quadrant: \(180^\text{o} 270^\text{o}\), $$ \text{Reference Angle} = Angle 180^\text{o} $$, Fourth Quadrant: \(270^\text{o} 360^\text{o}\), $$ \text{Reference Angle} = 360^\text{o} Angle $$, $$ \text{Reference Angle} = \pi Angle $$, Third Quadrant: \(\pi \frac{3 \pi}{2}\), $$ \text{Reference Angle} = Angle \pi $$, Fourth Quadrant: \(\frac{3 \pi}{2} 2 \pi\), $$ \text{Reference Angle} = 2 \pi Angle $$. What I want to Find. check out the law of sines ambiguous case Now we would notice that its in the third quadrant, so wed subtract 180 from it to find that our reference angle is 4. WebGiven the length of two sides and the angle between them, the following formula can be used to determine the area of the triangle.
