How do you simplify arctan (tan 3pi/4)? Socratic

Webcsc( 5π 4) csc ( 5 π 4) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosecant is negative … WebNov 5, 2015 · It equals -1 on the unit circle. This is because tan uses both sine and cosine ( sin cos) and in quadrant two, which 3π 4 sits in only cosine is negative making tangent a negative. Now that we have simplified it into arctan( − 1) we can find what special radian that is on the unit circle. Remember that arctan is limited to quadrants one and ... simplehuman system dish rack

Web9. Circle F has a central angle of 3pi/4 with radius 9 m. Find the area of the segment. 10. using the figure below,derive a formula in finding the Surface area of a cylinder a SA=4/3pi x r3b.SA=2πr2+2πrh 11. semicircular coneV =4/3pi 3(2)(15)() This is multiplication in other term 12. Please help me solve: sin(3pi). WebTo find the value of sec 3π/4 using the unit circle: Rotate ‘r’ anticlockwise to form 3pi/4 angle with the positive x-axis. The sec of 3pi/4 equals the reciprocal of the x-coordinate (-0.7071) of the point of intersection (-0.7071, 0.7071) of unit circle and r. Hence the value of sec 3pi/4 = 1/x = -1.4142 (approx) WebFree math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. raw natives
