3. Using basic identities, verify the identity. Show each step as a vertical "list" of steps. = coto sec 0 - sin 0 sin o cos
Use sum and difference identities to verify which of the following are identities. 1) sin(Q+8) - 1-tan & tan 8 sin a 2-cot a cot 8 2) cos(a+8) - 2 sin a sin 8 Both the equations are identities. None of the equations are identities Only the first equation is an identity. Only the second equation is an identity.
verify the following trigonometric identities. cos y 1-sın y 5, sec y + tany= cos x-sin x -cosx 1-tanx sinx cosx-l 7. sin20+cos 2 θ+ cot 2a 1+tan 2 θ 8.
please make answer clear and explain 6. (15 points) Verify EITHER ONE of the following identities (your choice). Circle the letter of the problem you want graded: either (a) or (b). Only one problem will be graded (though you can attempt both)-if your choice is unclear, (a) will be graded by default. (a) - sine 1+cos e sin 1+cos = 2 csc 8 ' (b) = 2 cott csct sect-1 Sect+1
1. (5 pts. Use identities to find the exact values of cos 0 and tan 0 if sin =- and is in the third quadrant. Show your work.
2 se the double-angle identities to verify the identity 1+cos(2x 2 cos* x = 9. Solve exactly over the indicated interval. a) sin(2x)-cos.x, all real numbers b) 2 cos(29) =-1, 0 θ < 2π
Solve for theta3!! Solve by elimination. Your Answer should start with arc-tangent. Use any trig identities if necessary. d-a*cos(theta2) +b*cos(theta3)=0 -a*sin(theta2) +b*sin(theta3)=0
6) Use the fundamental identities to find the values of sin(a), tan(a), and sec(a) if cos (a) 3 and tan (a)>0 5 (8 pts)
please help me and show all the steps and make sure it's correct [10pts.) 5. Find dy and the equation of the tangent line at the point (x,y)=(-2, 0) on the curve r = 21-sin(@)). Include a graph of the polar curve with the orienation indicated. dx [10 pts.) 6. Graph the polar equations r = 5 cos(30) and r = 3cos() for --/2S15 /2. Label any key points needed to find the area that lies in the common interior...
Use identities to find values of the sine and cosine functions of the function for the angle measure. V2 20, given sin 0 = and cos 0 >0 5 cos 20 = (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.) sin 20=0 (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.)
