Simplify tan theta [(sectheta,tantheta),(tantheta,-sectheta)]+sectheta[(-tantheta,-sectheta),(-sectheta,tantheta)] Iftanθ+secθ=1.5, findsinθ,tanθandsecθ. Ifa=secθ−tanθandb=secθ+tanθ, then View Solution IfA=[secθtanθtanθsecθ], then (secθ+tanθ)(secθ−tanθ...
对于\sin \theta \cos \phi,\cos \theta \sin \phi,\cos \theta \cos \phi,\sin \theta \sin \phi 都可以转化为两个一次的正余弦相加,所以就能积分。 Question 5: Find \int \sin 3 x \cos 2 x d x Solution: 因为 \sin 3 x \cos 2 x=\frac{1}{2}(\sin 5 x+\sin x) 所以 \beg...

\(\tan\theta=\dfrac{y}{x}\) 显然当\(P\)在第一象限即\(\theta\)为第一象限角时,三角函数的定义与之前相同,但是在平面直角坐标系中定义三角函数就使得其可以不受直角三角形的限制,扩展到任意象限角。 显然对于不同象限的角,\(\sin,\cos,\tan\)的值的正负是不同的: ...
sec(θ)=32sec(θ)=32,tan(θ)<0tan(θ)<0 The tangent function is negative in the second and fourth quadrants. The secant function is positive in the first and fourth quadrants. The set of solutions forθθare limited to the fourth quadrant since that is the only quadrant found in both...
tan(θ)=对边相邻tan(θ)=对边相邻 求单位圆三角形的斜边。由于已知相对边和相邻边,所以可以使用勾股定理求第三条边。 斜边=√对边2+相邻2斜边=对边2+相邻2 替换方程中的已知值。 斜边=√(−3)2+(5)2斜边=(-3)2+(5)2 化简根式内部。
