If tan theta = 10/9, and if cos theta is less than 0, find sin theta. If tan theta = 10/9, and if cos theta is less than 0, find sin 2 theta. If tan theta = 10/9, and if cos theta is less than 0, find sec theta. If cos theta = 2 / 5 and tan theta less than ...
Find an angle {eq}40^{\circ} < \theta < 360^{\circ} {/eq} with the same sine value as {eq}40^{\circ} {/eq} using reference angles. Identities of Sine Function: In trigonometry, the sine function follows a specific list of identi...
Solve for the angle theta, where theta is between 0 and 2pi. sin^2(theta) = (2 + sqrt(3))/4. Find the exact value of sin(\theta) given cos (\theta) = -\dfrac{1}{5}, \: 90^o < 0 < 180^o. Find theta if theta is between 0 degrees and 90 degrees. cos theta...

Q2.Evaluate the sine,cosine, and tangent of the angle without using a calculator.(If an answer is undefined, enter UNDEFINED.) 225° [2Marks] Q3.Find the period and amplitude. Sketch the graph of the function. [2Mark...
(180° – theta) = sin theta sin (180° –θ) = sin θ hence, there are three points that we can conclude here: 180° – θ will come in iind quadrant for any angle subtracted from 180°, sin will not be changed to cos the sign of sine ratio in the second quadrant will ...
My drawing did not have enough detail maybe because in the end the calculator for theta was correct. It was launched from a building 20m high which I did not include in the drawing, and the theta I calculated was the angle at the bottom near the impact site. Maybe that clears it up,...
(25)/7. Rearranging this equation results in sin(A) = sin(25)*12/7. Using a scientific calculator to find sin(25), carrying out the rest of the equation would show that sin(A) = 0.724. To find angle “A,” use the calculator to determine the inverse sine of 0.724. The answer ...
