Write the following in terms of sinθ and cosθ, then simplify if possible. {eq}\frac{\tan\theta}{\cot\theta} {/eq} Trigonometric Functions Trigonometric functions are functions that describe the relationship between the angles of a right-angle tria...
If x=a(sin theta+cos theta) and y=b(sin theta-cos theta) , then the value of x^2/a^2+y^2/b^2 is - यदि x=a(sin theta+cos theta) और y=b(sin theta-cos theta) , तो x^2/a^2+y^2/b^2 का मान क्या होगा ?
যদি sintheta=ksin(theta+phi) হয় তবে দেখাও যে, tan(theta+phi)=(sinphi)/(cosphi-k) ।
tan(θ)=2tan(θ)=2,sin(θ)<0sin(θ)<0 The sine function is negative in the third and fourth quadrants. The tangent function is positive in the first and third quadrants. The set of solutions forθθare limited to the third quadrant since that is the only quadrant found in both sets...
