Did you know?
WebTo solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for the variable. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions. Web`tan 7pi/12 = tan (pi/3 + pi/4)` You need to use the following formula such that: `tan(a+b) = (tan a + tan b)/(1 - tan a*tan b)` Reasoning by analogy yields:

Addition formula for tan: tan (x+y)= (tanx+tany)/ (1-tanxtany) let x=3pi/12=pi/4. let y=4pi/12=pi/3. tan (7pi/12 is in Quadrant II, therefore, it is negative. kia sportage service resetWebFeb 1, 2024 · Solve: 3sin^2 x - 2cos^2 x = 4sin x + 7 (0 < x < 2Pi). Solution. Replace in the equation (cos^2 x) by (1 - sin^2 x), then simplify the equation: 3sin^2 x - 2 + 2sin^2 x - 4sin x - 7 = 0. Call sin x = t. The equation becomes: 5t^2 - 4t - 9 = 0. This is a quadratic equation that has 2 real roots: t1 = -1 and t2 = 9/5. kia sportage shadow matte grayWebCos 7pi/12 can also be expressed using the equivalent of the given angle (7pi/12) in degrees (105°). We know, using radian to degree conversion, θ in degrees = θ in radians × (180°/ pi) ⇒ 7pi/12 radians = 7pi/12 × (180°/pi) = 105° or 105 degrees ∴ cos 7pi/12 = cos 7π/12 = cos (105°) = - (√6-√2)/4 or -0.2588190. . .
