State sign of tan 380 ° and cot 230 °
WebExplanation: For tan 2 degrees, the angle 2° lies between 0° and 90° (First Quadrant ). Since tangent function is positive in the first quadrant, thus tan 2° value = 0.0349207. . . ⇒ tan 2° = tan 182° = tan 362°, and so on. Note: Since, tangent is … WebThe cotangent graph has vertical asymptotes at each value of x where tanx = 0; we show these in the graph below with dashed lines. Since the cotangent is the reciprocal of the …
State sign of tan 380 ° and cot 230 °
Did you know?
WebBest answer i. 380° = 360° + 20° ∴ 380° and 20° are co-terminal angles. Since 0° < 20° <90°0, 20° lies in the l quadrant. ∴ 380° lies in the 1st quadrant, ∴ tan 380° is positive. ii. Since, 180° <230° <270° ∴ 230° lies in the 3rd quadrant. ∴ cot 230° is positive. iii. 468° = 360°+108° ∴ … WebFeb 8, 2024 · State the signs of cot sin 986° trigonometry class-11 1 Answer +1 vote answered Feb 8, 2024 by ShubhamYadav (44.6k points) selected Feb 10, 2024 by Architakumari 986° = 2x 360° + 266° ∴ 986° and 266° are co-terminal angles. Since 180° < 266° < 270°, 266° lies in the 3rd quadrant. ∴ 986° lies in the 3rd quadrant. ∴ sin 986° is …
