Cosine can be explained in different ways. The best explanation for why cosine start fraction 2 pi over 3 end fraction not-equals cosine start fraction 5 pi over 3 end fraction, is that;
- Cosine is negative in the second quadrant and positive in the fourth quadrant.
<h3>What Cosine is all about</h3>
Note that the sine of any angle in the second quadrant is said to range between 90 and 180 degrees and it is regarded as positive. But, if the cosine and tangent of any angle is said to be in this quadrant, it is regarded as negative.
The cosine function can be said to be positive only in the first and fourth quadrants. And the tangent function is known to be also positive in the first and third quadrants.

Explanation:
The way to position a client with a left hip fracture in Buck's traction is d) position the left in the center of the bed with the leg extended
<h3>What is Buck's traction ?</h3>
Buck's traction is a type of skin traction that is used to reduce pain and muscle spasms in patients with hip fractures or other lower extremity injuries. It involves applying a weight to the affected leg through a pulley system and a boot or splint that is attached to the skin.
To position a client with left hip fracture in Buck's traction, the following steps should be followed:
- Place the client in a supine position (lying on the back) with the head of the bed slightly elevated (no more than 30 degrees) to prevent sliding down the bed and increasing the traction force.
- Position the left leg in the center of the bed with the leg extended and aligned with the body. Do not bend the knee or hip of the affected leg, as this can interfere with the traction and cause complications such as nerve damage or skin breakdown.
- Secure the boot or splint to the left foot and ankle, ensuring that it is snug but not too tight. Check the skin integrity and circulation of the foot and toes regularly and report any signs of pressure ulcers, blisters, numbness, tingling, or color changes.
- Attach the weight to the boot or splint through a rope and a pulley system that is suspended from the foot of the bed. The weight should be prescribed by the physician and should not exceed 10 pounds. The weight should hang freely and not touch the floor or the bed frame. Adjust the height of the bed and the pulley as needed to maintain the proper traction and alignment of the leg.
- Place a pillow under the right calf from the knee to the ankle to prevent external rotation of the right leg and to maintain a neutral position. Do not place a pillow under the left leg, as this can reduce the traction and cause hip flexion.
- Position the client on the unaffected side with pillows between the legs to prevent internal rotation of the left leg and to provide comfort and support. Do not position the client on the affected side, as this can increase the pressure on the hip and cause pain and displacement of the fracture.
- Monitor the client for signs of complications such as infection, bleeding, nerve injury, or pulmonary embolism. Provide regular pain relief, skin care, and range of motion exercises for the unaffected leg and upper extremities. Educate the client and family about the purpose and care of the traction and the precautions to prevent further injury or complications."
