4 sin x + 4 cos x = 0 sin x + cos x = 0 sin x = -cos x The values of x which makes this true are additive inverses. Recall that sine and cosine are equal when x = 45 degrees. For these to be additive inverses, the angle x will lie in quadrants where x and y have different signs.

but what will be other ratios

3. Rohan28 Group Title

cosec x sec x tan x cot x

4. sirm3d Group Title

first, what is $$x$$ such that $sin x = -\cos x$ once you have that value(s), evaluate the other functions $$\sin x, \cos x, \tan x, \cot x\, \sec x,$$ and $$\csc x$$

5. Rohan28 Group Title

but tan tan x is coming cos/sin which should be sin/cos
