There are several ways in which you can find the slope of a tangent to a function. These include actually drawing a plot of the function and the tangent line and physically measuring the slope and also using successive approximations via secants. However, for simple algebraic functions, the qu...
( (sin)(x)(cos)(x)) , ( (0,2π )) 相关知识点: 试题来源: 解析 Replace the variable( x) with ( 0) in the expression. ( f(0)=(sin)(0)(cos)(0)) Simplify ( (sin)(0)(cos)(0)). ( 0) Since the computed y-value is not the same as the y-value given, the...
Draw the tangent line to the curve if required. Calculate the value of the tangent function for a second value of x such as x + 1 and draw a line between the tangent point and the second calculated point. Using the example, calculate y for x=3 obtaining y = 4*3 + 3 = 15. The ...
It’s also possible to convert an angle (in degrees) to slope; one must simply take the tangent of the angle. m = tan(θ) For example, if the angle = 72 degrees, then m is equal totan(72), which equals approximately 3.08.
Find ( (dy)/(dx)) and evaluate at ( x=1) and ( y=0) to find the slope of the tangentline at ( x=1) and ( y=0). ( 3/2) Plug in the slope of the tangentline and the ( x) and ( y) values of the point into the point-slopeformula( y-y_1=m(x-x_1)). ( y-...
