What is sin(x)+cos(x) in terms of sine? Socrati

sinx + cosx = Rsinxcosα + Rcosxsinα. = (Rcosα)sinx + (Rsinα)cosx. The coefficients of sinx and of cosx must be equal so. Rcosα = 1. Rsinα = 1. Squaring and adding, we get. R2cos2α +R2sin2α = 2 so R2(cos2α +sin2α) = 2. R = √2 Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor Free trigonometric equation calculator - solve trigonometric equations step-by-ste sin(A + B) = sin(A)cos(B) + cos(A)sin(B) Now let A = B = x. So we get: sin(x + x) = sin(2x) = sin(x)cos(x) + cos(x)sin(x) = 2sin(x)cos(x) Therefore, sin(x)cos(x) = (1.

Example 1 . Solve the equation sin x = cos x and then the inequality . sin x > cos x on the interval 0 x < 2.. From the unit circle we see that sin x and cos x can only have the same value in two places, in x = /4 and x = 5 /4 (45° and 225°). The equation sin x = cos x can also be solved by dividing through by cos x sinX/cosX + cosX/sinX = secX cscX I've been thinking that in the end both sides should somehow end up with 1/(cosX)(sinX) but I really don't know how to do that since the left side has addition and not multiplication so maybe I'm wrong?

Occasionally it can help to replace the original variable by something more complicated Another easy way to convert sin to cos (and vice-versa): sin (x) = 1/3. just look at the fraction: take the denominator squared, minus the numerator squared and take the square root of that whole thing. Divide that by the original denominator and there you have your cosine. So: Sqrt (3^2-1^2) / 3. You can do these exact same steps to convert.
